Whatever your views on the merits of Brexit, by the time it happens there won’t be many of our traditional food brands which are both owned and made in Britain.

Production is now controlled by overseas owners for a surprising number of the heritage food items bought regularly by Cumbrian shoppers.

People with a liking for potato snacks may remember Tudor Crisps.

The factory at Peterlee, in County Durham, which once made both Tudor and Smiths crisps, was shut on New Year’s Eve by Walkers which is owned by the giant American firm PepsiCo.

Around 350 jobs went at the factory, which had produced millions of bags of crisps over the past 67 years.

Tudor started at Newcastle in 1947 and TV adverts in the 1970s and 1980s gave it a cult status and the catchline of a “canny bag of crisps”.

Production ended in 2003.

Smiths crisps started life on London in 1920 and the company has been used by PepsiCo since the 1990s

British firm Premier Foods has its biggest shareholder – Nissin – in Japan.

Its familiar brands include Mr Kipling, Bisto, Oxo and Ambrosia.

Premier has a Batchelors Cup A Soup factory employing 360 people in Ashford, Kent.

Batchelors was established in Sheffield by William Batchelor in 1895 and specialised in canning vegetables.

By 1949 Batchelors brought out its first dried soup with a chicken noodle flavour and the company’s famous Cup A Soup range appeared in 1972.

Cadbury still has its international base at Uxbridge, West London, and operates in 50 countries but is owned by Mondelez International of Illinois in the United States.

It was established in Birmingham by John Cadbury in 1824.

Another sweets brand under the control of Mondelez is Maynards Bassetts, makers of the wine gums, jelly babies and liquorice treats enjoyed by generations of Cumbrians.

The Bassett firm was founded in Sheffield by George Bassett in 1842 – creating Liquorice Allsorts in 1899.

Its product mascot of Bertie Bassett was born in 1926.

Fellow British chocolate maker Rowntree’s was established at York in 1862 and is now owned by Swiss firm Nestle.

A historic factory making Colman’s mustard in Norwich is to be closed by the end of 2019 by its British-Dutch owners Unilever.

The historic link between the city and Colman’s would be retained by the production of mustard powder at a new site.

Manufacturing of other products would move mainly to Burton-upon-Trent but some work would switch to Germany.

Colman’s Mustard was started by Jeremiah Colman in 1814 at a site just outside Norwich and had been made in the city since 1858.

Carr’s famed Carlisle biscuits now belong to Turkish conglomerate Yildiz Holding, which has 300 brands spread across more than 130 countries.

This vast range of products includes United Biscuits, which acquired Carr’s in 1974.

Carr’s was established by Jonathan Dodgson Carr in 1831 and within 15 years was the biggest bakery business in Britain.
