BORIS Johnson is expected to walk into No10 on Wednesday as the new Prime Minister.
He'll spend his first 24 hours putting together his top team - a delicate balancing act which could make or break his premiership.
BoJo needs a balance of Leavers and Remainers, weighing up his supporters from the Tory right with the centrist "One Nation" MPs he also wants to win over.
And he'll want to avoid creating any powerful enemies, as Theresa May did when she sacked George Osborne.
Here we take a look at the possible make-up of the new Cabinet.
PRIME MINISTER - Boris Johnson
BoJo is known for his love of delegating, spreading power out among a team rather than hoarding it for himself.
He will reassemble his battery of aides from his time in Mayor of London, headed by Sir Edward Lister as chief of staff.
Mr Johnson's own role will be that of a "chairman" rather than a "chief executive", supervising all departments but not micro-managing.
CHANCELLOR - Sajid Javid/Dominic Raab
With Philip Hammond certain to be ditched, Mr Javid is favourite to take over as guardian of the nation's finances.
The current Home Secretary ran a spirited campaign for the leadership but has now backed BoJo in a boost to his chances of getting the Treasury job.
But there's also a chance Mr Raab could become Chancellor, if Boris decides he needs a staunch Brexiteer in the role instead.
HOME SECRETARY - Priti Patel/Andrea Leadsom
Assuming Mr Javid gets a promotion, a new face will be needed in the Home Office.
BoJo has promised to give a top job to a woman, meaning Brexiteers Ms Patel and Mrs Leadsom could be in the frame.
Both of them were in Mrs May's Cabinet - Mrs Leadsom resigned as Commons Leader in protest at her Brexit plans, while Ms Patel was sacked as Aid Secretary for holding secret meetings with Israeli politicians.
FOREIGN SECRETARY - Jeremy Hunt/Amber Rudd
Mr Hunt could stay in his current post despite his aggressive leadership campaign against Boris.
But if he does get moved, the job could instead go to Work and Pensions Secretary Ms Rudd in a sign BoJo is reaching out to Remainers.
DEFENCE SECRETARY - Penny Mordaunt
The Brexiteer has been praised for her performance as Defence Secretary since becoming the first woman to take the role earlier this year.
Sacking or demoting her would create a powerful enemy for the new PM and he will find it easier to keep her in the job.
BREXIT SECRETARY - Steve Barclay/Geoffrey Cox
Mr Barclay, the current Brexit Secretary, was one of the first Cabinet ministers to endorse Boris - which could help him stay in position.
Another contender is the widely respected Mr Cox, a top lawyer and staunch Brexiteer.
Under Mr Johnson, the Brexit Secretary's role will be to prepare Britain for a possible No Deal, rather than leading talks with Brussels.
BUSINESS SECRETARY - Liz Truss
The Chief Secretary to the Treasury is in line for a promotion after impressing Brexiteers in recent months.
She has been tipped as a possible Chancellor but the Business Department is a more likely destination after Remainer Greg Clark leaves the role.
HEALTH SECRETARY - Matt Hancock
Despite his Remainer background, Mr Hancock backed Boris after ending his own bid for the top job.
That means he's likely to stay as Health Secretary, the post he took over from Jeremy Hunt a year ago.
EDUCATION SECRETARY - Damian Hinds/Esther McVey
To avoid too much upheaval, the new PM may choose to keep the current Education Secretary Mr Hinds in his job.
Another candidate is Ms McVey, the former Work and Pensions Secretary, who put more schools funding at the heart of her failed leadership campaign.
HOUSING SECRETARY - Michael Gove
Although he fell out with BoJo in 2016, Mr Gove is expected to get a Cabinet position which will allow him to push through radical reforms as he did while Environment Secretary.
One possible destination would be the Ministry for Housing, Communities and Local Government which is tasked with helping more Brits own their own home.
WORK AND PENSIONS SECRETARY - Amber Rudd
Ms Rudd is influential on the One Nation wing of the Tory party - but crucially, has come round to the view that No Deal Brexit must stay on the table in talks with Brussels.
That should be enough to keep her in the Cabinet, keeping her current job even if she isn't promoted.
JUSTICE SECRETARY - Dominic Raab/Nicky Morgan
Ex-Brexit Secretary Mr Raab is highly likely to return to the Cabinet and his legal background could help him become Justice Secretary.
Ms Morgan is another former minister who previously worked as a lawyer and is keen for a Cabinet comeback.
TRANSPORT SECRETARY - Jo Johnson
With hapless incumbent Chris Grayling set to be sacked, the contentious post of Transport Secretary is likely to fall vacant.
One candidate for the department is Mr Johnson's brother Jo, who was a junior Transport Minister before he resigned last year.
ENVIRONMENT SECRETARY - James Brokenshire
If Mr Gove does move to MHCLG, it could spark a straight swap with Mr Brokenshire switching to Environment.
He's seen as a safe pair of hands who is respected on both sides of the Brexit divide.
INTERNATIONAL TRADE SECRETARY - Kit Malthouse
Liam Fox is another senior minister who is unlikely to survive Mrs May's departure.
Mr Malthouse, Boris' former Deputy Mayor of London, is a Brexiteer and experienced minister who is at the centre of thrashing out plans to replace the hated Irish backstop.
INTERNATIONAL DEVELOPMENT SECRETARY - Ben Wallace
One of BoJo's oldest allies, Security Minister Mr Wallace is expected to reach the Cabinet sooner rather than later.
Taking over from Rory Stewart as the minister responsible for the huge aid budget is one possibility.
CULTURE SECRETARY - Rishi Sunak
Although he only entered Parliament in 2015, Mr Sunak is highly respected as a junior minister and widely tipped for a Cabinet role.
The 39-year-old is married to the daughter of an Indian billionaire and became MP for Richmond after William Hague stood down.
NORTHERN IRELAND SECRETARY - Michael Fallon/Michael Gove
With Karen Bradley not expected to keep her job, the new PM will want a heavyweight figure in the sensitive position of Northern Ireland Secretary.
Sir Michael, the former Defence Secretary, is one contender while Mr Gove has also been rumoured to be on the shortlist.
SCOTLAND SECRETARY - David Mundell
The current Scotland Secretary is likely to keep his job by default because of the lack of alternative contenders.
WALES SECRETARY - Alun Cairns
Boris-backing Mr Cairns is also set to stay in the Cabinet under the new regime.
CHIEF SECRETARY TO THE TREASURY - Jacob Rees-Mogg/Mel Stride
If he's feeling bold, BoJo will hand the job of "deputy Chancellor" to Brexiteer star Mr Rees-Mogg - even though he's never held ministerial office.
A more cautious choice would be Mr Stride, the Treasury veteran promoted to Leader of the House of Commons in May.
ATTORNEY GENERAL - Geoffrey Cox/Robert Buckland
The job of being the Government's chief legal adviser is hugely important in the light of ongoing Brexit wrangling.
If he's not promoted Mr Cox will surely stay as Attorney General - otherwise the leading candidate would be Justice Minister Mr Buckland.
CABINET OFFICE MINISTER - Iain Duncan Smith/Michael Fallon
The role currently held by Mrs May's de facto deputy David Lidington is perfectly suited for a veteran MP with a remit to work across the whole Government.
Mr Duncan Smith, who is BoJo's campaign chair, could get the job - or Sir Michael could be handed the post instead.
LEADER OF THE COMMONS - Gavin Williamson
Managing parliamentary business will be one of the new Government's trickiest tasks.
As a former Chief Whip, Mr Williamson knows his way around the Commons and is experienced in holding the Tory party together.
CHIEF WHIP - Andrea Leadsom/Chris Pincher
Mrs Leadsom may be a candidate to take the lead in enforcing party discipline, after her well-received stint as Commons Leader.
Alternatively, Mr Pincher could be promoted from Deputy Chief Whip to replace his boss Julian Smith.

PARTY CHAIRMAN - James Cleverly
Although his leadership bid never got off the ground, Mr Cleverly - recently promoted from Deputy Chairman to Brexit Minister - is hugely popular among the Tory grassroots.
With a strong social media presence, he could help challenge Labour online and get the Conservatives ready for a General Election.
