Top Tory Jeremy Hunt has fuelled fresh speculation he will challenge Boris Johnson after he refused to say the Prime Minister was an "honest man".
The former Health Secretary said he "doesn't rule out a return to frontline politics" and when asked if Mr Johnson should remain as Conservative Party leader said he “hoped” so.
It comes after the PM was fined for breaking lockdown rules in Downing Street and after the Conservatives lost almost 500 seats in the local elections.
