Words by ITV News Westminster Producer Lewis Denison
Since taking office, Boris Johnson has relied on Cabinet ministers to take the lead on issues handled by their departments.
The prime minister seems quite happy to allow Dominic Raab to address the Commons on foreign policy points, Matt Hancock on health and Priti Patel on domestic issues.
But how many of his top team will be returning after Mr Johnson's first major Cabinet reshuffle of the year?
There are reports that up to a third could be on their way out when he makes changes expected next week.
Here's who currently has a job in government:
Zac Goldsmith - Culture Secretary
Former Conservative MP Zac Goldsmith, who lost his seat in the 2019 General Election, was made a life peer in December so he could retain his role as Boris Johnson's environment minister.
Former London mayor contender Mr Goldsmith lost his seat to the Liberal Democrats' Sarah Olney last week - with his support for Brexit likely playing a role in his defeat.
The 44 year old had a tough job of keeping his seat in the general election, having won a slight majority of just 45 votes in the 2017 snap poll.
Pro-Brexit Mr Goldsmith was always an awkward fit in a constituency that voted 72% Remain in the EU referendum.
At the December 2019 election, Ms Olney polled 34,559 votes compared to Mr Goldsmith's 26,793 on a turnout of 79% of the electorate.
Nicky Morgan - Culture Secretary
Nicky Morgan also retained her role in Cabinet following the election, despite no longer being an MP.
The culture secretary announced she would be standing down at the general election but Prime Minister Johnson made her a Conservative life peer in order to keep her in his Cabinet.
After being appointed, Ms Morgan joked that "leaving the Cabinet is harder than leaving the EU" and told her followers she was "delighted to continue" in her role.
Responding to the re-appointment, Labour MP Chris Bryant, a former shadow Culture secretary, tweeted: "It stinks. You abandon your constituents, eschew the tough work of representing a constituency but remain in the Cabinet.
"That really is two fingers up to democracy."
Ms Morgan first entered Parliament in 2010 and served as education secretary and minister for women and equalities from July 2014 until July 2016.
Simon Hart - Secretary of State for Wales
Simon Hart, who joined Cabinet after the election, first became a Conservative MP for Carmarthen West & South Pembrokeshire when he was elected in May 2010.
His most senior role before joining the Cabinet was Parliamentary Secretary at the Cabinet Office.
As Wales Secretary he took over from Alun Cairns, who resigned before the general election campaign over links to an aide accused of sabotaging a rape trial.
Sajid Javid - Chancellor of the Exchequer
As chancellor, ex-Tory leadership contender Sajid Javid is one of Boris Johnson's most senior Cabinet members.
He's played a big role for Mr Johnson so far, attending several events on behalf on the government, including the World Economic Forum in Davos.
He's already set a March 11 date for his first post-Brexit budget, meaning the Bromsgrove MP is likely to remain in Number 11 after the reshuffle.
Dominic Raab - Foreign Secretary
Ex-Brexit secretary Dominic Raab appears to representing the government on several fronts in his role as foreign secretary.
He's led the way on foreign issues, such as the case of Harry Dunn and the US woman who allegedly killed him in a car crash, but he's also been involved with other issues more recently, including Brexit.
Mr Raab was one of Theresa May's two resigning Brexit secretaries, stepping down in protest over her deal with the EU.
He ran to be Tory party leader, but was beaten in the race by Mr Johnson, who appointed him as foreign secretary.
Priti Patel - Home Secretary
Hard-line Conservative Priti Patel raised some eyebrows when she was appointed as Boris Johnson's home secretary.
She was fired as International Development Secretary in 2017 by Theresa May after holding secret meetings with Israeli officials.
But she was surprisingly brought back into the fray by Boris Johnson, possibly due to her support for Brexit.
Commentators claim Ms Patel could be one of the most senior ministers facing the chop.
Michael Gove - Chancellor of the Duchy of Lancaster
Despite a tumultuous relationship with Boris Johnson, Michael Gove is now effectively his right hand man in government.
The senior Tory is widely believed to have derailed Mr Johnson's first attempt at the leadership when he too announced he hoped to take over from David Cameron.
When Mr Johnson became prime minister, Mr Gove was appointed the government's lead in no-deal Brexit preparations.
Ahead of Brexit, Mr Gove's role was to lead the way in 'No Deal preparations'.
Now that the prime minister says a deal has been agreed, it is unclear what Mr Gove's role will be going forward, but he is likely to remain in Cabinet.
Robert Buckland - Justice Secretary
Robert Buckland is a relatively new face in the Commons, having only been elected in 2010.
He's been a constant frontbench face since 2014, serving as Solicitor General for England and Wales until 2019, when he was made minister of state for prisons.
When Prime Minister Johnson took over, Mr Buckland was promoted to justice secretary.
He recently made announcements in the Commons on new counter-terror legislation and spoke to the media about plans to allow camera's into courts.
Ben Wallace - Defence Secretary
Experienced Tory politician Ben Wallace previously served as the UK’s longest-serving minister for security and economic crime from 2016 to 2019.
He then took over from Penny Mordaunt, who was sacked as Defence Minister when Boris Johnson became prime minister.
He's most recently been in the news for reportedly disagreeing with Boris Johnson over his decision to allow Huawei into the UK's 5G network.
Matt Hancock - Health Secretary
Health Secretary Matt Hancock is one of the Tory frontbench's most prominent ministers.
He's addressed the House of Commons on several occasions recently around the coronavirus crisis and has made announcements around the NHS.Mr Hancock has had a prolific career in Parliament since being elected MP for West Suffolk in 2010.
He served under David Cameron in several different government roles before Theresa May took over and appointed him minister for digital and culture until he was promoted to secretary of digital, culture, media and sport.
He was promoted further when Jeremy Hunt became foreign secretary, making way for him to become the new health secretary, where he has remained since July 2018.
Andrea Leadsom - Secretary for Business, Energy and Industrial Strategy
Andrea Leadsom is a one of the Conservative Party's most well-known female politicians after challenging for the leadership following David Cameron's resignation.
She dropped out of the race, leaving a clear path for Theresa May to be elected unchallenged.
She served as leader of the House of Commons under Theresa May before resigning over Brexit in May 2019.
When Boris Johnson took over he invited her back into the Cabinet to serve as business secretary.
Elizabeth Truss - Secretary of State for International Trade
Elizabeth Truss was first elected as an MP in 2010 and has held government roles pretty much constantly since 2012.
She was Theresa May's chief secretary to the Treasury from June 2017 until July 2019 and was appointed trade secretary when Boris Johnson became prime minister.
Thérèse Coffey - Secretary of State for Work and Pensions
Thérèse Coffey was elected the Conservative MP for Suffolk Coastal in May 2010.
She was appointed to her most senior role in government - Secretary of State for Work and Pensions - when Amber Rudd resigned after Boris Johnson removed the whip from 21 Tory rebels.
Gavin Williamson - Secretary of State for Education
Despite being dismissed after being accused of a serious security breach when serving as Theresa May's defence secretary, Gavin Williamson found himself back in government when Boris Johnson took over.
He was appointed secretary of state for education in July 2019.
Before serving Ms May as defence secretary, Mr Williamson was her chief whip.
He was elected Conservative MP for South Staffordshire in May 2010.
Theresa Villiers - Secretary of State for Environment, Food and Rural Affairs
Having been elected in 2005, Therese Villiers is one of Boris Johnson's most experienced MPs within Cabinet.
She was transport minister from May 2010 until September 2012, when she was promoted by David Cameron to the role of Northern Ireland secretary until July 2016, when Theresa May became PM and stripped her of the role.
When Boris Johnson took over, he brought Ms Villiers back into government to serve as Secretary of State for Environment, Food and Rural Affairs.
Robert Jenrick - Secretary of State for Housing, Communities and Local Government
Robert Jenrick entered Parliament following a by-election in June 2014, making him one of the shortest serving MPs in the Cabinet.
He served as exchequer secretary to the treasury from January 2018 to July 2019, when he was made housing, communities and local government secretary by new prime minister Boris Johnson.
Grant Shapps - Transport Secretary
Grant Shapps was first elected to the Conservative MP for Welwyn Hatfield in 2005.
He was appointed Secretary of State for Transport on July 2019 and recently announced a move to nationalise rail operator Northern.
Julian Smith - Northern Ireland secretary
Before the premiership of Boris Johnson, Julian Smith was perhaps best known for being Theresa May's chief whip.
He worked for Ms May in the Chief Whip's office from November 2017 to July 2019, when Boris Johnson took over.
The new prime minister made Mr Smith Northern Ireland Secretary as one of his first appointments.
Alister Jack - Scotland Secretary
Alister Jack first entered Parliament as the Conservative MP for Dumfries and Galloway in 2017.
He was a Government Whip from April 2019 to July 2019, when he was appointed Scotland Secretary by Boris Johnson.
Baroness Evans of Bowes Park - Leader of the House of Lords
Baroness Evans was made a life Peer in September 2014 and served as a Baroness in Waiting from May 2015 until July 2016, when she was made Leader of the House of Lords.
Alok Sharma - International Development Secretary
Since becoming an MP in the 2010 general election, Alok Sharma has a colourful parliamentary career.
Before being appointed Boris Johnson's secretary of state for international development, Mr Sharma held diverse roles, ranging from the Prime Minister’s infrastructure envoy to India, to being the minister for housing and planning, for the Department for Communities and Local Government.
James Cleverly - Minister without Portfolio and Chairman of the Conservative Party
James Cleverly caused a stir when he threw his hat into the ring to become the next leader of the Conservative Party.
His bid for the leadership didn't last long after conceding it would be "highly unlikely" that he would win.
When Boris Johnson eventually did win, Mr Cleverly was appointed to the Cabinet, though his role is unpaid.
Steve Barclay - ex-Brexit Secretary
Steve Barclay was Theresa May's last Brexit Secretary and one of the few Cabinet ministers to stay in the same role when Boris Johnson took over.
Despite holding other roles in her teams, such as minister of state for health, Mr Barclay was relatively unknown outside Westminster before being appointed Brexit Secretary.
With the UK having left the EU, Mr Barclay's Department for Exiting the European has closed and his Cabinet role ceases to exist.
It is not clear whether Mr Barclay will return.
Does anyone else attend Cabinet?
There are several other senior Tories who attend Cabinet, though they are not officially Cabinet ministers.
Those include Leader of the House of Commons, Jacob Rees-Mogg, Chief Whip Mark Spencer, Attorney General Geoffrey Cox, and Business Minister Kwasi Kwarteng.
