:01:39. > :01:41.Four senior executives at Tesco were suspended this morning after the
:01:42. > :01:44.company admitted it had overstated its projected profits by nearly a
:01:45. > :01:47.quarter of a billion pounds. The announcement caused shock among City
:01:48. > :01:51.traders and shares in the UK's leading supermarket dropped by
:01:52. > :01:55.nearly 11% in early trading. Tesco has admitted that it's a "serious
:01:56. > :02:00.issue" and an internal investigation has been launched. It's not the
:02:01. > :02:03.company's only headache. Over the last two years Tesco has issued
:02:04. > :02:07.three profit warnings because competition from cut price
:02:08. > :02:19.Here's our business correspondent, Emma Simpson.
:02:20. > :02:26.Never mind the prices, it turns out Tesco has been getting its own
:02:27. > :02:30.numbers wrong. An accounting error to the tune of a quarter of a
:02:31. > :02:36.billion pounds emerged. The new boss has only been in the job for a few
:02:37. > :02:41.days, here at Tesco HQ and his first interview today wasn't the start he
:02:42. > :02:45.would have wanted. The early indications are ?250 million and
:02:46. > :02:49.based on that indication, that's the guidance that we've given, but I
:02:50. > :02:53.must stress I won't know until I have done the full investigation.
:02:54. > :02:58.Nor do I know what happened. It is a very serious issue. The news stunned
:02:59. > :03:03.the City. Tesco's share prices down over a third since the start of this
:03:04. > :03:08.year and today, it fell to its lowest level in over a decade. For
:03:09. > :03:13.this type of financial irregularity to be found at Britain's biggest
:03:14. > :03:18.retailer and a FTSE 100 company is shocking and unheard of and many
:03:19. > :03:23.people had their confidence in Tesco severely knocked at a time when
:03:24. > :03:27.people were already had a lack of confidence because of its recent
:03:28. > :03:31.poor performance. It is highly unusual for a company this big to
:03:32. > :03:36.declare an accounting error of this magnitude. It has got nothing to do
:03:37. > :03:42.with what's been going on here at the shops and an investigation is
:03:43. > :03:46.now underway to find out why Tesco overstated its profits forecast by
:03:47. > :03:52.bringing forward revenue from suppliers. It is the last thing this
:03:53. > :03:57.company needs. Sales have been falling and so too have profits. It
:03:58. > :04:01.is still Britain's biggest retailer by far, but Tesco has been losing
:04:02. > :04:06.shoppers especially to the discounters. This latest news is
:04:07. > :04:10.another blow. Today's story really raises questions over how Tesco has
:04:11. > :04:14.been governed and how the board is doing its job in overlooking things
:04:15. > :04:19.like finance. There is a lot of finance people on Tesco's main board
:04:20. > :04:22.and you would have hoped that through their various structures
:04:23. > :04:28.they would have picked up on an error like this. Was this a mistake
:04:29. > :04:36.or foul play? Tesco says it doesn't know yet and is promising to get to
:04:37. > :04:37.the bottom of it. For this retail juggernaut, the going has got
:04:38. > :04:41.tougher. Let's get more from our business
:04:42. > :04:44.correspondent, Simon Jack, who has been speaking to the Tesco
:04:45. > :04:55.boss, Dave Lewis. How serious is this? It is a big no,
:04:56. > :05:00.no in the City and the City punished them and their share price is down
:05:01. > :05:05.nearly 10%. The question is really that will be enough, but how is this
:05:06. > :05:11.company been run? As you say, he has only been in the job for less than a
:05:12. > :05:23.month so the questions to Philip Clarke, the Chief Executive and the
:05:24. > :05:28.new guy doesn't start for months. One of the most important companies
:05:29. > :05:31.was being run without a chief financial officer and the question
:05:32. > :05:34.is or the board, what were the audit committee doing? The people who were
:05:35. > :05:38.supposed to look at books to make sure they comply with the rules. I
:05:39. > :05:42.expect there to be question marks asked of the chairman of the board.
:05:43. > :05:46.On top of this, you have got, you know, you have got profit warnings.
:05:47. > :05:51.You have had the stock price sliding to its lowest in a decade. It looks
:05:52. > :05:58.like a business which once was formidable looks in total disarray.
:05:59. > :06:01.The Shadow Chancellor, Ed Balls, has told Labour Party members that he
:06:02. > :06:04.would have to take difficult economic decisions if the party wins
:06:05. > :06:07.the next general election. He has told the party conference he'll
:06:08. > :06:09.impose further cuts on child benefit and cut ministers' pay by 5%.
:06:10. > :06:16.From the party conference in Manchester, here's Chris Mason.
:06:17. > :06:21.At a football match between Labour and some supporters at the --
:06:22. > :06:28.reporters at the weekend, the man known as a political bruiser left
:06:29. > :06:32.one opponent needing stitches. Ed Balls knows as chancellor he would
:06:33. > :06:37.have to make cuts, but not quite like that. What's that? It is not
:06:38. > :06:43.blood this time, but paint as the Shadow Chancellor showed his softer
:06:44. > :06:48.side this morning, but it is neither as a bruiser he wants to be known,
:06:49. > :06:54.but as a manager of the economy. There will be no proposals for any
:06:55. > :07:00.new spending paid for by extra borrowing. We will not make promises
:07:01. > :07:06.we cannot keep and cannot afford. And that will mean more cuts. I want
:07:07. > :07:10.to see child benefit rising again in line with inflation in the next
:07:11. > :07:13.Parliament, but we won't spend money we can't afford. So for the first
:07:14. > :07:20.two years of the Parliament, we will cap the rise in child benefit at 1%.
:07:21. > :07:25.It will save ?400 million in the next Parliament. All the savings
:07:26. > :07:29.will go towards cutting the deficit. One children's charity said it sent
:07:30. > :07:33.out the wrong message. Treasury sources say he has got his maths
:07:34. > :07:38.wrong. How much of a saving is it? It sounds like a big number. It is
:07:39. > :07:43.?1 in every ?1,000 that we spend on benefits for people of working age.
:07:44. > :07:47.So it moves you in the right direction in terms of deficit
:07:48. > :07:50.reduction, but a small move in that direction.
:07:51. > :07:55.This speech just like all of the others we'll hear this week, boils
:07:56. > :07:58.down to this, it might look like a weather map, but it is a political
:07:59. > :08:00.map of Britain. The kind of places that Ed Balls and others have to
:08:01. > :08:06.convince to vote Labour if they're going to win the election.
:08:07. > :08:09.So Labour will attempt, again and again, to convince us it is not a
:08:10. > :08:18.gamble sending them back into Downing Street.
:08:19. > :08:23.Let's get the latest from Norman Smith.
:08:24. > :08:30.How did the speech go down? Well, it was the big speech on the economy,
:08:31. > :08:33.but it was a speech about trust because Labour insiders know many
:08:34. > :08:37.voters don't trust them on the economy and they do not trust Ed
:08:38. > :08:43.Balls to deal with the deficit. So the Shadow Chancellor was looking
:08:44. > :08:47.for a big, symbolic policy which was the equivalent of hanging a great
:08:48. > :08:57.big neon sign on the front of the conference centre which went, "Trust
:08:58. > :09:03.us." His hope is by announcing the curbs on child benefit that will
:09:04. > :09:07.convince us that he is serious about dealing about the deficit. Child
:09:08. > :09:12.benefit is paid to every family, but the richestful it goes into the --
:09:13. > :09:19.richest. It goes into the mother's bank account to help pay to bring up
:09:20. > :09:23.her children. This is just an extension of existing Government
:09:24. > :09:28.policy. The coalition has got a cap on child benefit. Secondly, it will
:09:29. > :09:32.only last for two years after that, child benefit will go up in line
:09:33. > :09:37.with inflation. So it may look tough. It may sound tough. But
:09:38. > :09:43.perhaps it is not quite that tough. Norman, thank you.
:09:44. > :09:47.After the No vote in the Scottish referendum, attention has turned
:09:48. > :09:50.this morning to the implications for England. David Cameron is hosting a
:09:51. > :09:53.summit of senior Conservative MPs to discuss plans to limit the voting
:09:54. > :09:56.rights of Scottish MPs in the House of Commons and to find an agreement
:09:57. > :09:58.over so-called "English votes for English laws".
:09:59. > :10:08.An English country house, the Prime Minister's residence. The scene
:10:09. > :10:13.today for talks today about the rights of English MPs and a promise
:10:14. > :10:18.made to stop Scotland from leaving the Union. More powers for Scotland
:10:19. > :10:22.were promised by David Cameron and the other Westminster leaders. No
:10:23. > :10:26.ifs, no buts, that will happen to a timetable they agreed says Downing
:10:27. > :10:31.Street. The Prime Minister also wants to look at whether Scottish
:10:32. > :10:35.MPs should carry on being allowed to vote at Westminster on matters that
:10:36. > :10:38.only affect England, but that may not happen as quickly and some of
:10:39. > :10:44.those meeting the Prime Minister at Chequers, insist you shouldn't give
:10:45. > :10:49.Scotland more powers whilst its MPs can decide on purely English matters
:10:50. > :10:53.at Westminster. It can not be ignored anymore. It is becoming an
:10:54. > :10:58.urgent issue. David Cameron may try to force a vote on that issue here
:10:59. > :11:01.in Parliament knowing that if he doesn't address the concerns he will
:11:02. > :11:06.have problems with some of his MPs, but he has created problems for
:11:07. > :11:10.Labour as well and that's probably no coincidence. Every time they try
:11:11. > :11:15.to talk about policy at their conference, they're asked about the
:11:16. > :11:19.constitution. We will look at any proposals people come forward with.
:11:20. > :11:23.That suits the Tories nicely. I want a fair distribution of moneys across
:11:24. > :11:27.England and we should look at how we reform our UK Parliament and that's
:11:28. > :11:31.why we're saying let's reform our constitution carefully over the next
:11:32. > :11:36.two years. In Birmingham, they think the issue matters. We should be
:11:37. > :11:39.looking at areas that we can work together, but I do think English for
:11:40. > :11:43.the English and Scottish for the Scottish and the Welsh for the
:11:44. > :11:49.Welsh. We voted to remain part of the UK and they should have a say of
:11:50. > :11:52.what goes on in England and Wales. The Westminster battle centres on
:11:53. > :11:54.whether Scottish MPs here should be stopped from voting on matters that
:11:55. > :12:01.will only affect the English. Our correspondent, Mike Sergeant,
:12:02. > :12:12.is outside Chequers. And what's chance of them reaching
:12:13. > :12:24.an agreement? Well, the meeting is underway and a glorious day. Some
:12:25. > :12:28.may say a quintessentially day. The MPs coming here today think there is
:12:29. > :12:31.a simple question of fairness if power is given to Scotland then
:12:32. > :12:36.devolution must happen for England as well. But what form that might
:12:37. > :12:40.take, well, that's not going to be settled over one lunch at the Prime
:12:41. > :12:46.Minister's residence. There are tricky questions that have taxed the
:12:47. > :12:49.filmest constituency -- finalest constitutional minds and Labour says
:12:50. > :12:54.the issues are so difficult and important, they should be taken in
:12:55. > :13:00.the round and considered carefully and if necessary, very slowly, but
:13:01. > :13:05.those Conservative MPs here sense real political opportunity in being
:13:06. > :13:06.seen to speak for England at this time of constitutional uncertainty.
:13:07. > :13:13.Mike Sergeant, thank you very much. Detectives investigating the
:13:14. > :13:15.disappearance of missing schoolgirl Alice Gross have been carrying out a
:13:16. > :13:18.fingertip search in the canal in West London near to where she was
:13:19. > :13:21.last seen. It's thought the main suspect, Arnis Zalkalns, may have
:13:22. > :13:24.returned to Latvia to go into hiding. Zalkalns was seen on CCTV
:13:25. > :13:27.cycling close to the spot where Let's speak to our correspondent,
:13:28. > :13:46.Richard Lister. And the search for Alice looks to be
:13:47. > :13:52.intensifying? Yes, police divers and forensic teams arrived here for a
:13:53. > :13:57.search of this river which is less than a mile from where Alice Gross
:13:58. > :14:00.was seen. These divers have been searching in the grid up and down
:14:01. > :14:04.the river as you can see, it is shallow at this point, but they have
:14:05. > :14:08.been moving that grid as they sweep a section of the river, moving it to
:14:09. > :14:14.a new section and continuing, but over perhaps, as you can see on the
:14:15. > :14:17.right of the screen, they've been, forensic officers have been
:14:18. > :14:20.searching that area and bagging up small pieces of refuse they have
:14:21. > :14:24.been finding and in the background, there have been other officers
:14:25. > :14:28.cutting hedgerows back with trimmers and searching those areas as well.
:14:29. > :14:32.Police say they have already searched nine square miles of land.
:14:33. > :14:35.They have searched about three-and-a-half miles of river and
:14:36. > :14:40.canal and they say 600 officers from eight forces are taking part which

:19:29. > :19:30.who have the most immediate and direct interest in fighting them.
:19:31. > :19:34.But I don't think we can in all circumstances rule it out,

:20:02. > :20:07.It is not necessary or wise to do that, but there may be situations -
:20:08. > :20:13.already there is an enormous help being given to those on the ground,

:20:30. > :20:32.It means someone's boots on the ground, for sure.

:22:04. > :22:07.mother was highly manipulative and controlling and would not let her
:22:08. > :22:11.daughter marry the man she loved. Instead of marrying without consent
:22:12. > :22:15.she had, in the words of the prosecutor, set out in a
:22:16. > :22:21.premeditated fashion to murder her mother. It is alleged that inspired
:22:22. > :22:27.in part by the US TV series Breaking Bad, she bought a deadly toxin from
:22:28. > :22:32.the USA over the internet, that the toxin had arrived concealed in a wax
:22:33. > :22:36.candle, and it is alleged she poured it into her mother's Tring. But the
:22:37. > :22:43.prosecution alleged nothing happened, that the poison was weaker
:22:44. > :22:49.if swallowed than inhaled or injected. They were told the FBI had
:22:50. > :22:52.arrested a man in the USA for selling the poison and pass
:22:53. > :22:59.information on to Scotland Yard and as a result of that, Konta Patel had
:23:00. > :23:02.been arrested. She denies attempted murder and acquiring a biological
:23:03. > :23:09.agent or toxin, but she has needed guilty to two counts of attempting
:23:10. > :23:11.to acquire a biological agent or toxin. The trial could last two
:23:12. > :23:15.Same-sex marriages were only made legal in March this year,
:23:16. > :23:17.but already criminal gangs are cashing in on them to help people
:23:18. > :23:21.An investigation by BBC London found criminal gangs
:23:22. > :23:23.were organising sham gay weddings for as much as ?10,000 a time.
:23:24. > :23:26.In some parts of London it's thought that as many
:23:27. > :23:38.as 20 to 30% of marriages are fake, as Mark Ashdown now tells us.
:23:39. > :23:45.In March, same-sex marriage is were finally recognised as legal.
:23:46. > :23:50.Congratulations, you may kiss the groom. A significant moment in
:23:51. > :23:58.history, but one that has opened the door for criminal gangs to exploit.
:23:59. > :24:03.We have been tipped off that a Romanian gang in London specialises
:24:04. > :24:08.in arranging sham same-sex marriage to dodge immigration laws. We sent
:24:09. > :24:12.an undercover reporter to pose as a would-be bride. The story is that
:24:13. > :24:19.she is an illegal immigrants seeking a fake marriage to remain in the UK.
:24:20. > :24:27.Our contact will pretend to be our uncle and act as go-between. We have
:24:28. > :24:33.protected his identity. These men are suspected and the talk quickly
:24:34. > :24:51.turns to business. Days later, at another meeting, a
:24:52. > :24:59.fake bride is provided. It is clear she is also in the scam. You
:25:00. > :25:06.understand this is for papers and you are no gay? No-go. These people
:25:07. > :25:12.have passed citizenship legally but the number of people willing to
:25:13. > :25:18.treat our growing. The thought is that up to 20 to 30% of marriages
:25:19. > :25:22.are to avoid immigration control. That only accounts for fake straight
:25:23. > :25:27.weddings. When it comes to gay marriage, registrars are struggling.
:25:28. > :25:30.It is difficult to detect. I would have thought that registrars would
:25:31. > :25:35.have some concerns they are performing ceremonies are not real.
:25:36. > :25:40.Our undercover bride is meeting her partner again, but she is not here.
:25:41. > :25:45.The gang says she is now involved in a different fake wedding. A
:25:46. > :25:54.different bride is here in pig and says she has helped in six different
:25:55. > :26:00.sham marriages will stop she even poses in fake photos. Weir I would
:26:01. > :26:06.expect this to be followed up by immigration enforcement teams. We
:26:07. > :26:11.are strengthening the law to better identify sham marriage worried may
:26:12. > :26:17.occur. As our fake bedding about to be registered, it is Peter and
:26:18. > :26:22.Ricardo taking centre stage. We want to have a chat about the marriages
:26:23. > :26:27.you a legally? They are unwilling to talk, but once the policy or
:26:28. > :26:29.evidence, they could each be facing up to 14 years in prison. -- once
:26:30. > :26:36.the police see evidence. Viewers in London can see

:26:43. > :26:44.arrived in orbit The Maven spacecraft is there to
:26:45. > :26:48.study how Mars changed from a planet with water and a thick atmosphere to
:26:49. > :26:52.the dry, barren planet it is now. Scientists think it may have
:26:53. > :26:53.happened because the planet lost its magnetic
:26:54. > :26:56.field around four billion years ago, as our Science Correspondent,
:26:57. > :27:12.Pallab Ghosh, now explains. NASA's latest mission to Mars...
:27:13. > :27:18.After a ten month journey, the Maven spacecraft is now in orbit around
:27:19. > :27:23.the Red Planet. Congratulations, XXX is in Mars orbit. Much to the
:27:24. > :27:32.delight of the team. We are in orbit of Mars, guys! It is cliches, people
:27:33. > :27:38.say it is not rocket science, but sometimes it is. This is what Mars
:27:39. > :27:42.was like 4 billion years ago - a habitable worlds with flowing water
:27:43. > :27:47.and thick clouds, similar in many ways to the Earth. Maven's mission
:27:48. > :27:53.is to find out how it ended up like this - the dry, dusty planet we see
:27:54. > :27:57.today. The climate has changed on Mars significantly over the last few
:27:58. > :28:01.billion years. We are trying to understand what the cause of the
:28:02. > :28:05.climate change has been. In essence, that is our goal - to answer the
:28:06. > :28:12.question, where did the water go? Word of the carbon dioxide go? Maven
:28:13. > :28:20.will be joined in two days time by an Indian spacecraft which will also
:28:21. > :28:24.analyse the atmosphere. With NASA's Curiosity on the ground, scientists
:28:25. > :28:27.will know more about the Red Planet than ever before. This will add up
:28:28. > :28:32.to enable us to figure out how humans will be able to go to Mars,
:28:33. > :28:39.survive for long periods of time, colonise the planet, literally over
:28:40. > :28:43.time. This spacecraft will spend a year in orbit over Mars taking
:28:44. > :28:49.detailed measurements of the atmosphere.
:28:50. > :29:03.We are doing pretty well. The high pressure that came in during the
:29:04. > :29:07.weekend, still the dominant feature. It is not doing enough to keep the
:29:08. > :29:10.weather front at bay from the north-western quarter of Scotland.
:29:11. > :29:15.That is producing rain. Elsewhere, as you can see, fine and dry
:29:16. > :29:18.weather. We are not being played on the eastern shores by that
:29:19. > :29:23.noticeable northerly wind we had yesterday. There is less cloud
:29:24. > :29:27.towards the Isles of Scilly and the western side of Cornwall. Lovely
:29:28. > :29:36.sunshine here for the afternoon. No more of the 2425 of last week, it is
:29:37. > :29:40.around 18, 19 or 20. The sunshine turning increasingly hazing across
:29:41. > :29:45.the north-western quarters of Northern Ireland. South eastern
:29:46. > :29:49.Scotland seeing the finest weather there. The weather front a feature
:29:50. > :29:54.for the Western Isles and areas north of the great Glen. That is
:29:55. > :29:58.until later this afternoon. Then it will gradually creep through the
:29:59. > :30:02.heart of Scotland and into Northern Ireland. To the north and south of
:30:03. > :30:07.that, the skies will stay pretty clear. Not a particularly cold night
:30:08. > :30:11.for the time of year in towns and cities but under the cloud, in
:30:12. > :30:17.double figures, just about. To either side, frost is possible. My
:30:18. > :30:21.concern about first thing tomorrow, the Somerset Levels into the West
:30:22. > :30:26.Midlands, maybe some fog patches or extensive than of late. A decent day
:30:27. > :30:29.across many central and southern areas. The weather front coming
:30:30. > :30:35.south through the day. Some moderate bursts of reigns as the clouds
:30:36. > :30:40.thickens. Towards the North West of Scotland, more showers. Those areas
:30:41. > :30:44.of cloud and rain merge and dissipate as they drift towards the
:30:45. > :30:48.British Isles during the course of Wednesday and then a lot more dry
:30:49. > :30:53.weather piling on behind those features. On Thursday, quite a
:30:54. > :30:57.number of isobars. Not very much in the way of rain. The weather fronts
:30:58. > :31:02.are in the Atlantic. Those isobars pointing towards the west and
:31:03. > :31:06.south-west, so breezy, but by day and night, relatively warm
:31:07. > :31:11.conditions across the British Isles. Bits of pieces of rain in the
:31:12. > :31:17.forecast but not a lot. The south staying mainly dry. More detail
:31:18. > :31:21.about the UK weather and the latest about the Tropical Storm Manuel has
:31:22. > :31:27.been going across Asia for the past few days. -- the tropicals or that
