Boris Johnson has refused to say that he will resign if Keir Starmer steps down over Covid lockdown rules.
The Prime Minister has found himself under mounting pressure to leave No10 after the Labour leader confirmed he'll quit if he receives a Fixed Penalty Notice (FPN).
In a statement at Labour HQ on Monday, Mr Starmer said he had always followed the rules throughout the pandemic - and accused his critics of cynical attempts to tar all politicians with the same brush after the PM was found to have broken his own lockdown rules.
