David Frost, Britain's Brexit minister, said London had proposed to Brussels an extension of a grace period from checks for foodstuffs such as chilled meats to help defuse a row over post-Brexit trade with Northern Ireland.

"I still sort of hold out some hope that they might agree to that," Frost told a parliamentary committee. "It does seem to us ... a very purist point for the EU to insist upon given that there is as far as we're aware no risk of great British sausages ending up in the single market."
