Boris Johnson is shaping a Government to deliver Brexit with a return to Cabinet expected for Eurosceptic Priti Patel and an advisory role for Leave campaign mastermind Dominic Cummings.
The new Tory leader will take over the reins of power after Theresa May leaves No 10 for the final time on Wednesday to formally tender her resignation to the Queen.
But even before his summons to the Palace to form a government following his resounding victory in the Tory leadership race, Mr Johnson was beginning to shape his top team.
It will include a recall to the cabinet for Ms Patel, an ardent Brexiteer who was forced by Mrs May to resign as international development secretary over unauthorised contacts with Israeli officials.
But uncertainty surrounds the future of Mr Johnson’s defeated leadership rival Jeremy Hunt after he reportedly turned down a demotion from Foreign Secretary to Defence Secretary.
One of the most eye-catching appointments expected to be made by Mr Johnson is a senior advisory role for Mr Cummings, the abrasive mastermind of the Vote Leave campaign.
Mr Cummings clashed with officials and politicians while he was an adviser to Michael Gove in the coalition government, but Mr Johnson clearly believes his forthright style will help steer Brexit through.
His appointment will be controversial given that earlier this year he was found to be in contempt of Parliament for refusing to give evidence to a committee of MPs investigating “fake news”.
He is also less than impressed with the calibre of Brexiteer MPs, describing a “narcissist-delusional subset” of the European Research Group (ERG) as a “metastasising tumour” that needed to be “excised”.
Mr Johnson will need the support of those same ERG hardliners for his Brexit plan.
Ms Patel has reportedly been lined up for the post of home secretary as allies said Mr Johnson was determined to create a “Cabinet for modern Britain”, with a record number of ethnic minority ministers and more women attending in their own right.
It is likely to mean a promotion for the Indian-born Employment Minister Alok Sharma, who is expected to take his place around the top table.
Unlike Ms Patel, he voted Remain in the 2016 referendum but was quick to declare his support for Mr Johnson when he threw his hat into ring following Mrs May’s decision to resign.
A source close to the Tory leader said: “Boris will build a Cabinet showcasing all the talents within the party that truly reflect modern Britain.”
A number of vacancies have opened up with the announcements by Chancellor Philip Hammond, Justice Secretary David Gauke and International Development Secretary Rory Stewart that they intended to resign before Mr Johnson takes office.
All three strongly oppose a no-deal Brexit and say they cannot support his commitment to take Britain out of the EU by the deadline of October 31 “do or die”.
Mr Gauke said there were “a few ministers leaving government today” but “some of us hope to return … one day” in a social media post accompanied by a picture of him and Mr Stewart with artificially aged faces.
Another who may be on his way out is the Business Secretary Greg Clark, another opponent of a no-deal break.
However, Mr Johnson is likely to be faced by a gaggle of Brexiteer ministers who resigned from Mrs May’s government now jostling to get back in – including Dominic Raab, Esther McVey and Andrea Leadsom.
Meanwhile, Home Secretary Sajid Javid and Treasury Chief Secretary Liz Truss were being touted as possible replacements for the key post of chancellor.
Mr Johnson has said he wants ministers who are prepared if necessary to leave the EU without a deal with Brussels.
But with a slender Commons majority for the Tories and their DUP allies of just two, he cannot afford for his government to be too narrowly-based.
Among the more junior ministerial ranks, promotions are expected for Local Government Minister Rishi Sunak, Cabinet Office Minister Oliver Dowden and Treasury Minister Robert Jenrick.
It’s time to get to work to deliver Brexit by 31st October, unite the party, defeat Jeremy Corbyn – and energise our country!

Tracey Crouch is expected to return to the front bench after she quit as sports minister last year.
Formal announcements are not expected until after Boris Johnson leaves the Palace following his audience with the Queen inviting him to form a government.
Before that, Mrs May will take Prime Minister’s Questions in the House of Commons for a final time and make a valedictory statement in Downing Street.
In a rare interview, Mrs May’s chief of staff Gavin Barwell said she viewed the prospect of no-deal Brexit as a threat to the United Kingdom staying together.
Former Tory MP Mr Barwell told BBC Radio 4’s Today programme that every time she visited Northern Ireland, Mrs May got a sense of a “real threat” to the union posed by Brexit and the lack of a devolved government.
“So, that is a real concern to her, yes,” he said.
On entering Number 10, Mr Johnson will also make an address to the nation – setting out his optimistic vision for the future for a post-Brexit UK.
Allies of Mr Johnson played down the prospect of an early election or a pact with Nigel Farage’s Brexit Party.
