The Tory leadership frontrunner is said to be wary of ministers who have now done a u-turn and backed no deal in order to get into his top team. Mr Johnson will be finalising decisions for his Cabinet should he win the leadership race, with the result just 10 days away. Some of his advisors are reportedly urging him to choose those who are fully committed to Brexit.
One senior ally told The Sun: “He knows his top priority is to deliver Brexit by October 31 or the wheels will come off the bus.
“Over the next few days he needs to pick ministers who are united in their desire to get us over the line come what may.
“Fail and we’re stuck in the road – and Boris is finished.”
Some of Mr Johnson’s allies are said to be suspicious of Amber Rudd suddenly dropping her opposition to a no-deal Brexit, as it could just be a move to save her career.
Other Tories facing uncertainty are Chancellor Philip Hammond and Brexit critics David Gauke, Greg Clark and Rory Stewart.
Mr Johnson’s leadership rival Jeremy Hunt could also be facing a demotion, as he wants a fully committed Brexiteer in the Foreign Office.
The source said: “Boris has made it clear he wants a Cabinet that is 100 percent behind leaving the EU on October 31, with or without a deal.”

11.01am update: Gina Miller confronted on new anti-Brexit plot – ‘Who on Earth do you think you are?’
Gina Miller recently wrote a letter to Boris Johnson which asked him to provide notice, should he become Prime Minister, if he plans to suspend Parliament and push through a no deal Brexit.
The businesswoman was confronted by Sky News presenter Niall Paterson over the letter, and questioned on whether it is another attempt to “thwart” Brexit.
Standing in for Sophy Ridge, Mr Paterson read out the letter to Mr Johnson from Ms Miller’s lawyers: “’We request that you undertake not to advise Her Majesty the Queen, should you become Prime Minister, to prorogue Parliament, without first providing 7 days’ notice to our client’.
“Don’t go and see the Queen if you are Prime Minister and prorogue Parliament. I mean, there will be people watching this this morning going ‘who on Earth do you think you are?’
“Writing a letter like that to the man who will most likely be the next Prime Minister.”
Ms Miller replied: “Each of us in a democracy, each of us have the right as a citizen to exercise our legitimate questions of the courts. And that’s what I did the first time.”
10.48am update: Jeremy Hunt says ‘I am the one to negotiate a viable Brexit deal’
The Foreign Secretary has said he appeals to “people who might vote Conservative, not just those who already do”.
He wrote in the Sunday Telegraph: “I know your biggest priority is to deliver Brexit. Here I ask you to vote with your head and not just your heart.
“Approach the negotitations in the wrong way and we will get an election not Brexit. The quickest way to leave is not by offering a deadline Parliament could stop butby negotiating a deal it will accept.”
10am update: Tory chairmen cast aside neutrality to endorse Boris
A group of 68 chairmen, deputy chairmen and presidents of Tory associations have signed a joint letter to The Sunday Telegraph to say they believe Boris Johnson is the man to deliver Brexit.
They say that the party would be facing “the chaos of Jeremy Corbyn and Nigel Farage”, as well as an emboldened SNP in Scotland without Mr Johnson’s leadership.
The open letter from association officers to members said: “We would… urge you to vote for Boris Johnson in the leadership eelction because he will build a team that delivers Brexit, defeats Corbyn and unites our party and our country.
“He represents the true Conservative values that have been the foundation of our succes and these will enable Britainto move beyond Brexit and build a brighter future.”
9.42am update: Chancellor warns no-del Brexit will leave UK ‘at mercy of French’
Chancellor Philip Hammond has warned the French would be able to “dial up” or “dial down” at will the queues for goods going into the port of Calais if there is a no deal Brexit.
He said Paris would be able to exploit the Channel crossing to exert pressure in the same way that the Spanish had used the border with Gibraltar.
Despite spending more than £4 billion on Brexit preparations, Mr Hammond told a BBC Panorama special there would be a limit to the amount of influence the Government could exert in the event of no-deal.
Asked if the UK could control Brexit, the Chancellor said: “We can’t because many of the levers are held by others – the EU 27 or private business. We can seek to persuade them but we can’t control it.
“For example, we can make sure that goods flow inwards through the port of Dover without any friction but we can’t control the outward flow into the port of Calais.
“The French can dial that up or dial it down, just the same as the Spanish for years have dialled up or dialled down the length of the queues at the border going into Gibraltar.”
