The son of a Pakistani immigrant bus driver, Javid moves from the role of home secretary to another of the UK's Great Offices of State — Chancellor of the Exchequer. He actually backed Remain in the 2016 referendum. As the UK’s finance minister, the Deutsche Bank veteran replaces Philip Hammond, who quit hours ahead of Johnson's appointment.

Raab, who resigned from Theresa May's government in opposition to the divorce agreement struck with Brussels while he was Brexit secretary, was named Britain's foreign secretary — one of the most senior roles in government. Raab also takes on the mantle of first secretary of state, meaning he will deputize for Johnson when the prime minister is absent.

Patel, an arch-Brexiter and former minister, returns to government as home secretary — the title given to the UK's interior minister. She's seen as a hardliner within the party on most matters, not least Europe. Patel, who was fired by May for having secret meetings with the Israeli government, was a staunch opponent of the former prime minister's withdrawal deal.

Hancock was among the initial contenders to replace Theresa May, but he didn’t last long in the race. Although he campaigned for Remain during the referendum, Hancock has said he now believes Britain should leave the EU. He's one of a few former Remainers who gets to stay.

The fact that Johnson's former Vote Leave colleague Gove, who moves from the environment brief, finds a place in Cabinet could be seen as a surprise. He was responsible for derailing Johnson's post-referendum leadership bid in 2016, before standing for the leadership himself. The Cabinet Office role means he will be close to Brexit negotiations, and preparations for a no-deal Brexit.

A former chief whip, Williamson was sacked as defense minister in a stinging letter by Theresa May earlier this year. He allegedly leaked details of a government deal involving Chinese company Huawei, but strongly denied this. He now takes over the education portfolio.

Despite it being his first Cabinet post, Rees-Mogg is one of the most recognizable faces of the pro-Brexit camp in Parliament. As chair of the European Research Group, he actively pressured Theresa May's government to implement Brexit. MP for a rural English constituency, the son of a media baron, a staunch Catholic, and an old Etonian like Johnson, Rees-Mogg's background is in investment banking.

A devout Brexiteer, Leadsom was a prominent member of the Leave referendum campaign. She has twice run for Tory leadership and failed — reaching the head-to-head with Theresa May in 2016. An interview gaffe led to her quitting the race before it really began, allowing May to take office unopposed. She was promoted to leader of the House of Commons thereafter, and now takes another step up.

Wallace, a lesser known Scottish lawmaker, started his political career as a Member of the Scottish Parliament. Beforehand, he served in the British military for eight years, during which he was deployed to Germany and Northern Ireland, among others. In the run-up to Brexit, he campaigned for the Remain camp. Reportedly, he was Johnson's second choice. Jeremy Hunt is said to have refused the job.

Rudd is one of few survivors from the ancien regime, staying in the same post as Work and Pensions Secretary. In the run-up to the Brexit referendum, she campaigned for the UK to remain. She previously served as home secretary under Theresa May and was seen as a close ally of the former PM. She famously stood in for May, who declined to take part, at an election debate against Jeremy Corbyn.

Jo Johnson is an anti-Brexit lawmaker and Boris' younger brother. Jo quit his former Cabinet post in protest at the terms of the proposed deal to leave the EU, and has advocated a second referendum on whether to actually leave. As his brother once was, long ago now, he's seen as a left-leaning, europhile member of the Tories.
