Newly appointed British Chancellor Nadhim Zahawi has called on Boris Johnson to "do the right thing and go now".
It's the latest call for the embattled British Prime Minister to resign.
He has now lost more than 50 members of his government in two days - Northern Ireland secretary Brandon Lewis is among the latest to go.
Mr Johnson's understood to be planning a Cabinet reshuffle this morning - although one source says some members of his team have started drafting a resignation statement.
Political Commentator Adam Boulton says he's behaving like the last US president.
"It's absolutely fair to say that Boris Johnson is acting in a Trumpian manner, resisting all the evidence that he is not wanted any more and he should quit.
"We don't have a written constitution in this country, but by all political norms it is fairly routine for the Prime Minister to be changed in office by the members of the ruling party."
