Campaigners say they appreciate attempt to use Cornish but mistake points to need for more access to language

Shoppers in Cornwall could have been forgiven for feeling bemused after a supermarket put up bilingual signs – in Welsh.

A branch of Tesco in Helston – about 200 miles from south Wales by road – pointed shoppers towards pysgod, which is Welsh, not Cornish, for fish. It also labelled sweet potato as tatws melys – again Welsh instead of Cornish.

Cllr Loveday Jenkin, a leading member of the political party Mebyon Kernow, which campaigns for greater self-government for Cornwall, said she was pleased Tesco had put up bilingual signs.

“But would have been more exciting if they had been in Cornish rather than Welsh,” said Jenkin. She popped into the Tesco – her local – on Wednesday to thank customer services for the effort but request that the right Celtic language be used.
