Waitrose has ruled out buying American beef and chicken amid fears the country could be flooded with foreign meat following Starmer's US trade deal.

The supermarket giant made the commitment to 'stand with British farmers' after Sir Keir agreed to cut tariffs on US beef imports.

Pete Navarro, Donald Trump's trade counsellor, last week branded European food standards a 'phoney tool used to suppress what is very fine American agricultural product'.

The comments come despite fears there will be a watering down of food safety standards to allow products such as hormone-treated beef or chlorinated chicken into British stores - though the UK Government insists this will not be the case.

British and US officials agreed to a deal that gives American farmers a quota to import 13,000 tonnes of beef that meets UK welfare standards.
