Boris Johnson news - live: Brexit deal breach may harm US relations, PM told, as he stands by Trump Nobel claim

Boris Johnson has admitted there are "teething problems" in the post-Brexit trade relationship between Britain and Northern Ireland as industry experts warned there could be fresh shortages on supermarket shelves in the province.

The prime minister vowed to trigger Article 16 of the Northern Ireland Protocol if necessary to stop supermarkets running short of food, attacking “absurd’ bureaucracy.

But a Conservative MP warned him his promise not to hesitate in taking unilateral measures risked "huge damage to the Good Friday Agreement....and damage the relationship between our country and the US”.

Any breach of the Brexit accord that may undermine the Good Friday agreement risked harming the UK’s relationship with the US and Joe Biden, Mr Johnson was told.

In an appearance at the Liaison Committee, Mr Johnson also avoided a chance to take back his claim that Donald Trump should find himself in line for a Nobel Prize.

Earlier he committed to a review of the supply chain that led to families on free school meals receiving meagre hampers which Sir Keir Starmer claimed were based on government guidelines.
