Prime Minister Boris Johnson carried out a reshuffle of his cabinet on Wednesday, removing several key ministers including Gavin Williamson.
This is the second major reshuffle since Mr Johnson became leader of the Conservative party and took over as prime minister from Theresa May in July 2019. The last one took place in February 2020.
Some of the big moves included Liz Truss to foreign secretary, the Tories' first woman in that role; Nadhim Zahawi moved from leading the vaccine rollout to education - at the expense of Mr Williamson; and Nadine Dorries stepped up from health minister to culture secretary.
Who's in the other posts? Here's a guide to the people that make up Mr Johnson's cabinet, with the latest new faces and who's changed places.
Boris Johnson's cabinet
Boris Johnson became prime minister in December 2019 and immediately faced the UK's looming exit from the EU and the start of the coronavirus pandemic.

As well as Mr Williamson, Mr Johnson removed three other members of the cabinet: Robert Jenrick, who was housing secretary; Robert Buckland, who was justice secretary; and Amanda Milling, who was Conservative Party co-chair - although she has been handed a ministerial role at the Foreign Office.
Dominic Raab, who had been the foreign secretary, was demoted to justice secretary.
According to data from ConservativeHome, Mr Williamson was the least popular member of the cabinet with Conservative party members. Liz Truss, who has been promoted to foreign secretary from international trade secretary, was the most popular.
The make-up of the cabinet has also changed with all the comings and goings.
There are two more women then there had been before the reshuffle, but the proportion has stayed about the same because the overall number of people attending cabinet has also increased slightly.
As for the education of those now in cabinet, about 63% of them went to private schools, down slightly when compared to Mr Johnson's previous reshuffle last year - but still a stark contrast to his predecessor's.
Just 30% of Theresa May's first cabinet in 2016 attended independent schools, which was fewer than both Tony Blair and Gordon Brown's original cabinets.
According to the Sutton Trust social mobility charity, every prime minister since 1937 who attended university was educated at Oxford - except for Mr Brown.
At 43%, Mr Johnson's new cabinet has slightly fewer members who were educated at Oxford or Cambridge compared to his last reshuffle - but it's still more than double what is was in Tony Blair's first cabinet in 1997.
