High Street food shop Pret A Manger is to stop selling tuna sandwiches after its boss was horrified by a hard-hitting new film about how intensive fishing methods are destroying the seas.
Pret founder Julian Metcalfe says tuna and cucumber sandwiches will be taken off the menu at his 155 British shops.
He has also banned endangered bluefin tuna from sushi boxes sold at Pret and its sister outlet Itsu.
Mr Metcalfe’s tuna sandwich ban comes on the eve of the premiere at 50 cinemas across Britain tomorrow of The End Of The Line, a hard-hitting documentary about overfishing inspired by a book by environmental journalist Charles Clover.
