13/02/2017 Inside Out Yorkshire and Lincolnshire

Tonight on Inside Out, we go undercover at Britain's

biggest supermarket, Tesco.

And we go in search of gold in one of the unlikeliest of places.

Welcome to Inside Out, I'm Paul Hudson.

Tonight, we are investigating Tesco, Britain's biggest supermarket,

where some special offers aren't always that special after all.

Also tonight, the artist hiding real treasure

And later in the programme, top archaeological finds

You can see he's got quite a wide rood here,

and that's probably something like an axe.

Now, how often do you check your receipt when you shop at Tesco?

We all take for granted the price we see on the shelf

is what we pay at the till, but what if it's not?

Well, Jonathan Gibson has been investigating

the not-so-special offers at Britain's biggest supermarket.

That's why the shelves at Britain's biggest supermarket

are full of special offers - money off this, buy two for that,

you get the drift, and we all take it for granted that the price we see

on the shelf is the price we'll pay at the till - right?!

But what if things don't quite add up when you get home

I've just bought a few bits at Tesco and I'm sure these products

were on special offer - that's why I've bought two of each -

but according to my receipt I've paid full price!

I've paid 60% more than the deal on the shelf.

At another Tesco store, I spot 2 for ?2.00 on ice cream.

But at the till, it's the full price as well, so what's going on?

Martin works for Trading Standards and says the law

They must put a price on goods so you know what you're going to pay

and that price must be accurate so you don't get charged

more than you thought you were going to pay.

Sounds simple enough and with more than 3,500 stores nationwide,

That's what I want to find out so armed with my phone and some

secret cameras I want to see how many offers on the shelves don't go

through at the checkout, and here in Leeds I'm finding problems.

After checking the price on the shelf he asks his colleague

But neither of the staff remove the out-of-date label so,

when my colleague returns a few hours later, we're

Multi-buy deals are being left on the shelves after the tills have

This offer is almost a month out of date and it's not

At this Tesco superstore on the outskirts of Leeds,

a worker checks the label but he doesn't spot

It should have been removed five days ago.

I've started making a list of how many offers are wrong in how many

places and I want to know if what's happening in Yorkshire is also

Because, if it is, it's not just a problem for Tesco,

At this Tesco store in Liverpool, sauce marked ?1 on the shelf

And at another store nearby, I'm left completely confused

by the offers on the shelves and what I'm charged

In fact, there's so much difference between the shelf price

and the receipt price, I'm not even going to bother

to go back and try to get what I'm owed returned.

If there are just too many offers changing too frequently so that

store staff can't really be expected to understand them, comply

with all the changes, then that is something that Tesco

And there's plenty to think about when I head back to Leeds.

Doing now what somebody should have done hours, days, weeks ago.

That's a serious message but is everyone taking it seriously?

And as I head around the country, the same thing keeps happening,

It doesn't seem a terribly difficult or perhaps that long a job,

just to walk round the store, assuming everyone knows

what day it is, you know, to go round and tear off anything

And it's not just shoppers left confused as old and new promotions

The longer the offer has been wrong, the bigger the failure of diligence

and the more worried I am, frankly.

In that case, he's not going to like what's coming up next.

At this store, the cashier checks the out-of-date label

And when I return the next day, neither does someone else.

So, a week later, I go back, and it's still on display.

And when I return a month later, yes, still on the shelf.

The fourth worker finally removes it.

It's pretty basic that if one customer is shown something wrong

then it's put right to stop other customers being misled.

But at 33 of the 50 stores I went to, the till price was more

If customer A has come back and complained and been refunded,

that doesn't mean there weren't 20 other customers who didn't spot it

There were obviously major problems with their control of the special

offers and it's the special offers that bring people in,

make people reach for more and perhaps spend a little bit more

than they're meant to when they came into the store,

The company wouldn't provide anyone for interview

but after reviewing our evidence told this programme...

Following our investigation, Britain's biggest supermarket says

it's now doublechecking the accuracy of every price in every store -

that's more than 3,500 stores across Britain.

And don't forget, if you've got any comments about the night's programme

or you've got a story you think we might like to cover,

you can get in touch on Facebook or on Twitter.

Coming up on Inside Out, the archaeological treasures hidden

Now, there's a chance to find some modern-day treasure

An art exhibition is opening in the town.

The paintings will contain clues to a very special treasure hunt.

Anyone can take part and the prize is real gold, I kid you not!

It's winter in Scunthorpe - not the most promising place to be

But later this week, people here will have

a golden opportunity - quite literally.

We've got five golden artefacts that have been created.

They are going to be hidden in and around Scunthorpe.

But to find them, you'll need to crack a code.

One of them is supposed to be ridiculously easy.

Each gold object is worth ?1,000 and if you find it you keep

It's all in the name of art and Luke Jerram is the artist behind

I had this idea to think about celebrating the history

of Scunthorpe by taking five objects from the museum and created

So tell me about the statues themselves.

They range from a Jurassic ammonite, which will be millions of years old,

all the way through to a genus train, which is taken

We've also got a Roman ram and this beautiful Tudor figurine as well.

But finding these ?1,000 solid gold objects will not be that easy.

Treasure hunters will have to crack a code which is hidden in paintings

to be displayed at the 2021 Gallery in Scunthorpe.

And the paintings are being created at this not-so-secret

Each artefact has a painting that goes with it, and the painting

contains clues as to where to find this gold artefact.

There are five paintings and five objects.

Luke has asked artist Vivienne Baker to make the five paintings.

Today he's come to take a look at how things are progressing.

Not that surprisingly, all the clues will be in gold.

Yeah, it looks nice, though, doesn't it?

The paintings are like backgrounds, like something solid

There's no way I could crack the most difficult one.

I could certainly crack probably two or three of the paintings.

You say that now you know the answers!

I've been working with a guy from an unnamed government agency

to work out all the coding and the ciphers for these paintings.

Some are really easy to decode whereas the most

complicated painting, it will take maybe a month

I know you're not giving a lot away, you don't want us to suss

out the clues just yet, but can we speak to the man?

So I've managed to persuade Luke to give me the details for his code

man and now I'm heading back up North to meet him.

I'm at Sheffield University to meet mathematician and secret code

How on earth does a mathematician get involved with an art

Well, it was quite a surprise, really.

One day, there was an e-mail going round.

The header was just puzzler/codebreaker required.

I just tried to resist the temptation to open it but I failed.

How many people know the answers to the codes?

How difficult are the cyphers that you've set within them?

So there are five in total and one of them is supposed

The final two in particular are much harder, so we're expecting at least

one of them to go unsolved for quite a while.

To give me a fighting chance, Dan shows me how to solve

So what I've used here is something called a Caesar shift.

It's a very old cipher and basically all I've done is I've took

the alphabet and I've shifted it on one place.

This one follows a bit of an extended rule from that one,

so can you try and figure that one out for me?

that's a jump forward, that stays the same,

that's a jump forward, that stays the same.

Well, I don't think they'll be recruiting me for MI5 any time soon.

We took the file, we printed it and now we need to put a feeder

Meanwhile, at a secret location elsewhere in the country,

some very talented people are working to finish the gold

objects ready for them to be hidden in five locations around Scunthorpe.

Originally, it's a Viking brooch that was found

It reminds me of all the wind turbines in Scunthorpe.

We are putting the wax into the mould.

We are going to melt the wax out of the mould.

And then, through that tube, we will feed the metal to make the piece.

Right, ready to go, and we will roll it over.

There is this lovely moment of alchemy when you're holding

precious metal and you're melting it down and it's being transformed

into another form, there's something quite magical about that.

We've gone from a 3D object to scanning to wax into plaster

Look at that, solid gold worth ?1,000, I wonder

So I'm off to meet the man whose job it is to organise the exhibition.

We are in Scunthorpe Centre. We close to where any figures are

hidden? There are some in urban locations, some in parkland and some

a bit further out of town. You worried that people will dig up all

the parks? It was a concern so we were very careful not to bury any of

the objects. It will be difficult to hide them. Should we go in

balaclavas in the middle of the night? We're not sure. He might have

to shake your bid. So, if someone finds the object

they get to keep it, and they will then decide

whether to melt it down Or they can keep the artefact

for artistic reasons, so that's interesting as well for me

what the value of an object is, is it just the value of the gold

or does it have more value as an artefact, as an artwork

in its own right? hiding the objects under the cover

of darkness, but you've guessed it, The exhibition starts

here in Scunthorpe at the weekend Now, most people know

the Yorkshire Wolds for its rolling hills and stunning views,

but it has got another claim to fame - as one of Britain's richest

archaeological sites. We sent intrepid explorer

Paul Rose to investigate. With thousands of acres

of lush farm land - you could be forgiven for thinking

that all you'll find in the Wolds But just a few feet below

the surface of this chalk rich landscape there are epic stories

of the black death, extreme violence They're all there if

you dig deep enough. I'm going to take a journey back

in time through the wolds - a place that has provided some

of the country's most significant It's very productive landscape in

prehistoric times as is the day, and all that activity has left its mark.

You can go back through time periods, whether it is prehistoric

Mesolithic material through the Bronze Age, the Iron Age, the

medieval period, the Romans, and see how humans have shaped informed that

landscape. The most famous of the wolds'

archaeological sites is the deserted medieval village

of Wharram Percy near Malton. And here there's still

lots to actually see. For 700 years, there was an active

community here, and this is what remains of the church and hub of the

whole village. A combination of the Black Death and the way the lad was

farmed meant that by the early 16th century the village was effectively

abandoned. Archaeologists have had a field day

trying to understand In the 1950s researchers moved in,

and they stayed for 40 years You are not just looking at the

building or a castle. You are looking at the every day, how these

people ate, had they produced food, how they lived. That makes the

excavations stand out because it gives all that contact the daily

lives of ordinary people. People like us.

The Wharram Percy dig is now over but, nearby on the wolds,

archaeologists are still hard at work.

from Manchester University are working on an extraordinary cold

case that's taken me even further back in time to the iron age

I am on the Trail of the burial that was found when it was snowing in

1980. Originally discovered by members of the Army. The excavated

what they thought was a shell and it turned out to be an iron sword.

It was an amazing find of the lost burial site

of what appeared to be a significant figure.

The grave occupied a prime position with grand views all round.

And the fact the sword was bent but not broken was probably a sign

that the weapon was ALSO laid to rest along with its owner.

It's a dramatic burial with the sword Ben. We can imagine the wood

of the scabbard shattering around the blade. So this man somehow had a

place high in society? I think so. I want to understand his life as well

as his death. Mel's team are looking for more

clues near the burial site but what's clear is that this

warrior met a violent end. First, I am going to show you his

skull, it is very fragile. His remains have made the short

journey to Hull Museum. That fine line has healed, so that

the sharp thin blade. It goes hand-in-hand with an injury at the

back of his head, which is a much larger wound. He has got a wide

wound here and that is something like an axe. Its gates across the

scalp, he gets away with it. Unfortunately, the next time he

meets the sharp end of the sword, he does not survive. We have got three

injuries at the back of the head, or one there, and another one at the

top of the head, quite deep pond. He may have died by the sword

but new data has shown that this man Can you see that discolouration on

the rip? There, particularly, can you see how bumpy it is? It looks

almost like dirt. It should not be there. It is as body reacting to

severe infection. The warrior had tuberculosis -

a debilitating chest infection that Scientists believe it's the second

earliest case of TB to have Whether there's a conflict and he is

so poorly he is unable to defend himself, whether members of his own

community despatching because they do not want this disease to spread,

they are worried, they may even see him as being cursed by the gods,

another possibility is he may want to grab death the throat, go out in

the glorious end, and it is snowing that his comrades will promise him

the sender. That's quite something. While some stories take

ages to piece together, others are uncovered

by mother nature. Close to one of the world's great

superstructures is the site of one of the Wold's most

remarkable discoveries. Ted and Willy Wright -

found planks sticking out of the mud The wood looked like it

was once part of a boat but how old it was -

well, that came as a complete The shape of the boat at the

brothers to believe it was a Viking craft but the reality was much more

exciting. This boat was over 4000 years old. These planks were

situated in a gloopy, horrible mud. How they manage to do it. What a

complete and utter nightmare. The gloopy mud acted

like a preservative playing a key part of the survival

of what remained. Over the course of several decades,

three boats were discovered - and their design has led historians

to believe they were capable They were plank built boats made out

of seven or eight planks. All three boats show a base plank with planks

attached to the side of it and they are literally tied together. We have

got evidence were they are driving in Moss to make the boats

weatherproof. The world built by skilled craftsmen. They were at the

front end of the technology at the time. In terms of technology, these

are incredibly advanced. What is absolutely beautiful about them is

you can see how we use that technology in wooden boat building

today. That is extraordinary, that was 4000 years ago. To me, it is not

surprising. This watercourse was the heartbeat of this area, it was the

difference between life and death. This was a trade in goods and

material and people and ideas. Finding these boats has given us a

unique insight as to life in those times? Absolutely. They showed us

that not just look but outwards, out beyond the Humber Bridge we see

today. These days, we enjoy

the Yorkshire Wolds for its natural But beneath our feet,

there are thousands of secret stories, and one thing's for sure,

what's been found so far has only scratched the surface of the hidden

history of this corner of England. And you can see more Paul Rose
