The move comes as the Prime Minister has been witnessing criticism with several Tory MPs aiming to rebel against the 57-year-old leader. Five new MPs from the 2019 General Election are now thought to have written letters to demand Mr Johnson quits.
It comes as the PM’s personal rating fell by 11 points in less than a month — with YouGov finding his approval score at a new low of -41.
MPs have been spotted going to see backbench boss Sir Graham Brady to demand a leadership election.
Ex-Tory chief whip Andrew Mitchell has urged the PM to “get a grip” to keep his job.
He told Times Radio: “I hope he will still be Prime Minister in a year — but if Downing Street doesn't get a grip and start to deliver the governance many of my colleagues are talking about openly, then the PM will be in considerable trouble.”
But one angry minister hit back at the Tory newbies, telling The Sun: “It doesn’t take long before these kids forget who got them their seat.”
On Thursday, Boris Johnson was forced to placate his standards adviser after being accused of lying about the lavish makeover of his Downing Street flat.
Lord Geidt, the PM’s independent adviser on standards, probed the spruce-up earlier this year.
However, fresh evidence has emerged that Mr Johnson may have known the true source of decorating donations earlier than he claimed.

Lord Geidt is said to be “furious and humiliated”.
On Thursday he was understood to be considering relaunching the probe.
Last week The Sun reported as many as a dozen Tory MPs want a change of leader, still far short of the 56 required to formally trigger a contest.
Meanwhile, Mr Johnson’s senior spin doctor, Jack Doyle, offered to resign over the ongoing row after last year’s lockdown-breaking wine and cheese event for No？10 staff.
