SIR KEIR STARMER’S prostration before Donald Trump looks set to receive a humiliating rebuff as the US president announces tariffs on the British economy.

The Prime Minister has been almost alone among world leaders in refusing to criticise the erratic Mr Trump in the hope that Britain would be spared from his economic warfare.

Yet Sir Keir conceded that it was likely that Britian will be hit by the tariffs due to be unveiled by Mr Trump today, which could amount to a tax of 25 per cent of value on all goods entering the US.
