Asda has introduced traditional potato varieties, unavailable in British shops for the last 40 years, to its shelves.

British Queen, a potato first developed in 1894, is valued for its fine flavour, shape and floury texture, while Red King Edward, a rarer relative of the more common King Edward potato, was developed in 1916. Arran Victory, a purple-skinned potato was developed in the Arran Isles in 1918 and named to celebrate the end of the war.

"Older varieties can be susceptible to disease and produce far fewer tubers - but many believe they still provide the best eating potatoes available," said Asda potato buyer Drew Kirk.
