Boris Johnson's popularity among Conservative MPs and members of the wider Tory party membership landed him the top job he has long coveted.

The former mayor of London has previously held only one cabinet position, foreign secretary, under Theresa May.

But Mr Johnson, a leading Brexiteer, was at odds with Mrs May’s Brexit vision and eventually quit the role in protest last year.

She has argued that it would be in the EU's best interests to reopen negotations, as a way of securing any of the £39bn so-called divorce bill.

Ms Patel resigned from the cabinet In November 2017 following a row over unauthorised meetings with Israeli politicians. Her departure followed hot on the heels of Defence Secretary Michael Fallon, plunging Theresa May's cabinet into turmoil.

She was first elected to the seat of Witham, Essex, in 2010, after working for several years in PR for the Conservative Party, as well as lobbying for tobacco and alcohol industries.

As well as being made foreign secretary, Dominic Raab has been appointed the first secretary of state.

The staunch Brexiteer, who has been tipped for high office since his election as an MP for Esher and Walton in 2010, has insisted that Brexit must happen on 31 October whether there is a deal or not.

The former lawyer was appointed as a justice minister in 2015, but was sacked by Theresa May when she became prime minister the following year.

After David Davis’s resignation as Brexit secretary in July 2018, Mr Raab was appointed as his successor. He quit only months later in opposition to Theresa May’s Brexit deal, which he said he couldn't “in good conscience” support.

During the leadership campaign he was forced to address questions surrounding cocaine use. He said it had been a mistake and he deeply regretted taking it at social events 20 years ago, while working as a journalist.

The MP for Surrey Heath, since 2005, was a key ally of former Prime Minister David Cameron. He made his name as a radical education secretary, bringing in major changes to exams and the curriculum and battling teaching unions during his four years in the role.

In 2016, he famously scuppered the leadership hopes of his friend and fellow Brexiteer Boris Johnson, by announcing his own candidature on the morning Mr Johnson was due to launch his campaign.

Mr Gove became environment secretary in June 2017 and he proved a key advocate of Mrs May’s Brexit deal, while other Brexiteer cabinet ministers resigned.

Former security minister Ben Wallace, who campaigned to remain in the EU, has warned that a no-deal Brexit would hit UK-EU security ties and have a "real impact" on protecting the public.

Ms Truss was elected to Parliament in 2010 after serving as deputy director of think tank Reform.

The former defence secretary was sacked by Theresa May in May after a row over the leaking of information from the National Security Council.

But Mrs May said she had lost confidence in him in light of “compelling evidence” suggesting he was responsible for the “unauthorised disclosure”.

Despite this setback, Mr Williamson remains a key power broker within the party, having served as a ministerial aide to David Cameron and then as chief whip, in charge of party discipline. At that time, he famously kept a tarantula named Cronus on his desk in the House of Commons.
