Who are May's key Cabinet appointments?
Chancellor Philip Hammond: In one swift announcement George Osborne was out and former Foreign Secretary Philip Hammond was in as Chancellor of the Exchequer. He has previously served as Transport Secretary and Defence Secretary. The "reassuringly boring" choice, Mr Hammond is viewed as holding a devout belief in economic stability and prudent public finances. In opposition he was labelled the Tories public spending axeman.
Foreign Secretary Boris Johnson
After a prominent role in the Brexit campaign, he was tipped to become Prime Minister. But he pulled out of the race when Michael Gove made a surprise announcement he was to run. His political fortunes have turned following Ms May's decision to give him one of the most sought-after roles in the Cabinet. The former Mayor of London was an unexpected appointment and was prone to gaffes overseas.
Secretary of State for Brexit David Davis
In holding the newly created role, Mr Davis - a long-time Eurosceptic - will lead negotiations for Britain's exit from the EU. He has previously published a "Brexit economic strategy for Britain". Mr Davis has served as Foreign Office Minister and shadow home secretary.
International Trade Secretary Liam Fox
He was forced to resign as Defence Secretary in 2011 after allowing his friend Adam Werritty to take on an undeclared role as his adviser. Five years on he has been welcomed back into the ranks by the new prime minister. Regarded as right-wing, he ran in the Tory leadership contest but was quick to back Ms May when he was eliminated in the first round.
Home Secretary Amber Rudd
Ms Rudd came to politics later in life than most, having worked as an investment banker, venture capitalist, and financial journalist. The former Secretary of State for the department of Energy and Climate Change was a loud voice for Remain during the EU referendum. She appeared to support the new Prime Minister over her own junior minister Andrea Leadsom in the race for the Tory leadership.
Defence Secretary Michael Fallon
He had been tipped as a possible candidate for promotion but Ms May appeared to give her seal of approval to his work in the past two years by keeping Mr Fallon in his current role.
