The products that Unilever claim are being pushed up in price by Brexit which are made in the UK

HALF-A-DOZEN of the products which Unilever claim must rise in price because of Brexit - including Marmite and Pot Noodle - are made in the UK, The Sun Online can exclusively reveal.

The global consumer goods company is in the middle of an almighty row with Tesco, after Britain’s biggest supermarket refused to swallow a 10 per cent price increase.

Unilever then stopped supplying stock to Tesco, leaving the supermarket short of many products.

However, Grocery insiders have warned that Unilever is using Brexit as an “excuse” to raise prices, as many of its products are made in the UK.

The Sun Online has tracked down six everyday Unilever products that are found in UK households which are made in this country.

A factory in Burton-upon-Trent, Staffordshire produces 6,000 tons of Marmite each year - around 50 million jars - and is home to the controversial breakfast spread.

The factory, which also makes another iconic Unilever product, Bovril has helped the area earn the glowing title of ‘the brewing capital of Great Britain’.

Elsewhere, Unilever elves are hard at work in Crumlin, South Wales stirring up batches of Pot Noodle.

The student staple has been made in the area since 1979. In 2002, Unilever said that it was producing 175 million pots per year - that means an estimated five pots were being wolfed down every second.

In Manchester, PG Tips is made in the Brooke Bond factory in Trafford Park.

The best selling tea brand was sold to Unilever in 1983, but the location is still home to its tea factory.

Another, cupboard staple, Colman’s Mustard has been based in Norfolk ever since Jeremiah Colman started his mustard and flour business in 1814 in Stoke Holy Cross.

The company was bought by Unilever in 1995 and continues to be produced on the original site.

Walls - the ice cream - is a subsidiary brand of Unilever, some of its products are made in a purpose built factory in Gloucester, the cathedral city of the Cotswolds.

So, how has Brexit pushed up supermarket prices?

In June, Unilever’s chief executive Paul Polman warned that a vote to leave the EU's single market would increase prices for consumers.

Today, its finance chief again warned that the price of popular products will rise as a result of the collapse in sterling.

Supermarkets have multi-million pound deals with suppliers such as Unilever and the details of which are a secret.

Although, Tesco’s big chief, Dave Lewis, a former Unilever executive, said last week that he was limbering up for a fight with suppliers who tried to use the falling pound to push through price increases.

He accused brands of failing to pass on the benefit when sterling was strong and was “uncomfortable” with efforts to raise prices on the way down.

Last month, the Bank of England warned that the effect of Brexit could have on food prices.

It said that supermarkets were having to come up with ways to hold prices at pre-referendum levels.

However, the problem is much more complex. While many of the items which are made in the UK are sourced from all over the world - these “raw materials” are usually bought and sold using dollars, or even euros.

The value of the pound has fallen by 17 per cent against other currencies since the vote to leave the EU in June.

This has pushed up the cost of raw materials. These costs, as long with packing and distribution, could be pushing up the price for UK shoppers.

The Sun Online contacted Unilever for a comment.
