Boris Johnson was flying to the UK from his Caribbean holiday to attempt an extraordinary comeback as prime minister after telling an ally he is “up for it”.
Trade minister Sir James Duddridge said the man who stood down six weeks ago after being ousted by his own cabinet following a series of scandals has told him “we are going to do this”.
The Tory MP said Mr Johnson will land back in Britain on Saturday and will challenge to replace Liz Truss as Conservative leader.
But the development will not be welcomed by all Tories, with former leader Lord William Hague warning Mr Johnson’s resurrection would lead to a “death spiral” for the party.
Sir James, who served as one of Mr Johnson’s parliamentary private secretaries at No 10, told the PA news agency: “I’ve been in contact with the boss via WhatsApp.
“He’s going to fly back. He said, ‘I’m flying back, Dudders. We are going to do this. I’m up for it’.”
The MP for Rochford and Southend East was confident that Mr Johnson will get the 100 nominations from Tory colleagues to make it to the next stage of the contest “quite quickly”.
Sky News photographed the ex-PM and wife Carrie Johnson on an overnight British Airways flight back from the Dominican Republic with their children and said the MP received “one or two boos” as he boarded.
Commons Leader Penny Mordaunt is the only candidate who has officially declared she is running, but former chancellor Rishi Sunak is also expected to launch a challenge.
Sir James said Mr Johnson will argue he is “the only person that’s got a mandate” from the 2019 general election and that he can “bring the party together”.
Mr Johnson has “learned and reflected” during less than two months out of office, and knows he needs a No 10 operation that is “slicker” and has “command of the details”, according to the ally.
Sir James said Mr Johnson knows he needs a “government of all talents” and would “welcome back with open arms” even those who “said despicable things about him”.
Mr Johnson was picking up support from Cabinet ministers, including Jacob Rees-Mogg, Anne-Marie Trevelyan and Simon Clarke.
But Lord Hague, a Tory peer, said Mr Johnson returning is “possibly the worst idea I’ve heard of” during his 46-year party membership.
“I think it’d be a very, very bad idea to bring Boris Johnson back,” he told Times Radio.
“This all started, this unravelling, because Boris Johnson was unable to run the government in the right way, to keep it together in the right way, to uphold the high standards of conduct that are necessary in the highest offices in the land.
“Him returning is the solution? That would be going round in circles and that could become a death spiral of the Conservative Party.
“And I think it’s possibly the worst idea I’ve heard of in the 46 years I’ve been a member of the Conservative Party.”
