:01:12. > :01:18.London does suffer from episodes of very high pollution once or twice
:01:19. > :01:21.a year but this is the first time the mayor has issued an alert.
:01:22. > :01:24.He says he is trying to tackle the problem through policies

:04:56. > :04:57.passed since the horror of the Holocaust, for some,
:04:58. > :05:02.the memories are still vivid. At City Hall, they
:05:03. > :05:08.remembered the victims. But the Mayor is among
:05:09. > :05:11.those worried that today in 2017, in this city, people
:05:12. > :05:15.are being targeted just because they This brick with a swastika emblem
:05:16. > :05:19.was hurled through the window of a family in North West London
:05:20. > :05:22.this weekend, one of four We have zero tolerance
:05:23. > :05:27.towards hate crime. The police are looking
:05:28. > :05:31.at CCTV footage, they are speaking to Jewish
:05:32. > :05:34.communities to reassure them, we are taking this very seriously
:05:35. > :05:40.and we will get to the bottom of it. On Friday afternoon the police
:05:41. > :05:47.discovered anti-Semitic graffiti One group which tries to tackle
:05:48. > :06:04.Jewish hate crime thinks abuse online is going
:06:05. > :06:07.unpunished and leading Today, social media is a cauldron
:06:08. > :06:14.of which the current wave of anti-Semitic hatred
:06:15. > :06:16.is being brewed. Social media has been wonderful
:06:17. > :06:18.in many respects, but it has also given voice
:06:19. > :06:21.to many people who want to promote all manner
:06:22. > :06:23.of anti-Semitic conspiracy theories. The Met say they have not seen
:06:24. > :06:26.the evidence yet to prove these latest incidents are linked,
:06:27. > :06:34.but say it is of huge concern the Jewish community

:06:50. > :06:51.the Nazis in the 1940s, she is deeply saddened
:06:52. > :06:54.by this we can's events. Because I have seen a lot
:06:55. > :06:59.of anti-Semitism and I have seen the result of it,
:07:00. > :07:04.people have witnessed the Holocaust. Also this weekend,
:07:05. > :07:07.an advert on the tube for a film about Holocaust
:07:08. > :07:10.denial was defaced. So far no one has been
:07:11. > :07:13.arrested over any of these Turning now to the restoration
:07:14. > :07:21.of the Houses of Parliament, Well, the cost of some
:07:22. > :07:29.of the proposals would be so high that it seems some people
:07:30. > :07:32.would rather see it demolished or sold off,
:07:33. > :07:35.as Sonja Jessup tells us. Shrouded in a London fog today,
:07:36. > :07:38.the Houses of Parliament providing Slightly spoiled, perhaps,
:07:39. > :07:42.by scaffolding, and inside, crumbling stonework,
:07:43. > :07:46.ageing electrics - parts of the Palace of Westminster
:07:47. > :07:51.are in desperate need of repair. It will cost almost ?4 billion -
:07:52. > :07:54.a price worth paying? A quarter of people asked said
:07:55. > :07:57.they would rather it was I'm sure there are some people
:07:58. > :08:04.who would quite like to put a match But it is interesting that the vast
:08:05. > :08:08.majority of the public, more than 56%, in the same poll,
:08:09. > :08:13.said we've got to do the work, we should do the simplest,
:08:14. > :08:16.the swiftest and the most cost-effective way of doing that,
:08:17. > :08:18.and I believe that is, we've all got to move out for six
:08:19. > :08:22.years, get the work done as quickly And that is the recommendation
:08:23. > :08:27.from the committee he serves on. MPs would move to a temporary
:08:28. > :08:32.building at Richmond house, Actually demolishing the historic
:08:33. > :08:36.Palace of Westminster is not an option being considered,
:08:37. > :08:41.though the poll's findings may hint at those disillusioned
:08:42. > :08:45.and angry with politics. There are others who believe
:08:46. > :08:47.Parliament is worth preserving, The idea of pulling that down,
:08:48. > :08:53.such a symbol of world democracy and world liberty,
:08:54. > :09:10.is just unthinkable. Politicians are being told
:09:11. > :09:17.parliament faces crisis if the repairs are not carried out.
:09:18. > :09:20.I'll wish you a very goodnight now and hand you over to Wendy
:09:21. > :09:32.Still some fog in the forecast. The weather for the week ahead is not
:09:33. > :09:38.much changing that nothing to sweep the Fog away. It is remaining cold.
:09:39. > :09:44.There will be some frosty mornings again. Yes, it will be foggy. The
:09:45. > :09:48.Met Office has asked other by a weather warning overnight up until
:09:49. > :09:53.around 11 o'clock tomorrow morning with dense and freezing fog patches
:09:54. > :09:58.here and there which may impact on our transport and make for difficult
:09:59. > :10:07.driving conditions. The most widespread will be under clearer
:10:08. > :10:10.skies south west of London. We are under cloud at the moment and it
:10:11. > :10:13.will take a break in that cloud for fog patches to form. It will be
:10:14. > :10:19.another cold start to the day tomorrow. Probably quite dank,
:10:20. > :10:23.especially where the Fog has formed. It should lift and break away and we
:10:24. > :10:28.will have sunshine into the afternoon temperatures on the cool
:10:29. > :10:35.side. You can see of blue tinge on the map. Another cold front follows
:10:36. > :10:40.on. This is Wednesday. A bit more cloud which will eradicate some of
:10:41. > :10:44.the fog issues. Still feeling quite chilly, especially so on Thursday,
:10:45. > :10:48.despite there being sunshine around and despite the numbers in the box
:10:49. > :10:53.is not looking very different. It would be a cold and dry wind blowing
:10:54. > :10:58.in. That will make it feel really quite bitter on Thursday. The
:10:59. > :11:02.temperature will pick up on Friday. A hint of something rather to come.
:11:03. > :11:04.For the weekend we will have dry weather with sunny spells and it
:11:05. > :11:16.will be a little bit milder. Good evening. We are continuing to
:11:17. > :11:24.see huge righty in the weather. Getting the detail right is proving
:11:25. > :11:29.to be a challenge. This was in Pembrokeshire and other parts of the
:11:30. > :11:35.UK were gloomy throughout the day. The fog is thickening up right now.
:11:36. > :11:43.Particularly pool on the M5 in south-west England. Very foggy
:11:44. > :11:48.across parts of the West Country. This fog is tending to spread its
:11:49. > :11:52.way further eastwards. Some fog as well across parts of Yorkshire.
:11:53. > :11:58.Northern Ireland and Scotland are mild but damn. This is how we will
:11:59. > :12:00.start the day. At eight o'clock in the morning, quite a lot of fog
:12:01. > :12:02.around which could affect the major
