A survey of Conservative activists earlier this month for ConservativeHome found that Johnson had dropped back in popularity, falling into fourth place behind Rees-Mogg, Davis, and justice minister Dominic Raab.

Johnson put himself back in the spotlight after setting out his Brexit vision in a 4,200 word article ahead of May's big speech this month.

That racked up controversy over his referral back to the claim that Brexit would allow the government to plough £350m a week back into the NHS. That led to Sir David Norgrove, head of the UK Statistics Authority, criticising Johnson for a "clear misuse" of government figures, while home secretary Rudd said he was "backseat driving".

And yesterday it emerged the Prime Minister was being urged to investigate whether the foreign secretary had broken the ministerial code with the claim.

The majority of Conservative members in the survey said they wanted May to step down as leader, with 64 per cent wanting her to leave before 2022. That is despite the PM's pledge that she will fight next the next General Election.

Some 13 per cent called for her resignation before Britain has left the European Union.
