The Brexit Opportunities Minister, a key ally to the outgoing Prime Minister, claimed it was “not realistic” to think Mr Johnson could make a return to Downing Street. Mr Johnson announced he would stand down as Prime Minister pending a Tory Party leadership contest in July after he faced a Cabinet cabal.
However, the Uxbridge & South Ruislip MP has repeatedly hinted about a potential return to Downing Street.
During his final Prime Minister’s Questions, Mr Johnson said it was “probably… certainly” his last despatch box bout against Labour leader Sir Keir Starmer.
He also claimed his “mission” was “largely accomplished – for now”.
Jacob Rees-Mogg, who formerly chaired the pro-Brexit European Research Group, told GB News why he thinks Mr Johnson will be unable to stage a comeback.
The North East Somerset MP, who is backing Tory leadership frontrunner Liz Truss in the race to replace Mr Johnson, said: “Nobody’s come back having lost the leadership of the party since Gladstone.”
Mr Rees-Mogg added: “And I just don’t think in modern politics, the chance of coming back is realistic.
“Lots of people think they’re going to be called back by a grateful nation which is why Harold MacMillan waited 20 years before accepting his peerage… Life just isn’t like that.”
However, Mr Rees-Mogg’s comments come while the Sunday Mirror has claimed Mr Johnson and many of his allies are plotting a return to Downing Street if Ms Truss “implodes”.
A source said: “I think that could well intensify if things go badly for Liz – you get people thinking ‘Would he have been any worse?’
