David Cameron has maintained continuity at the top of Government after he re-appointed four senior Conservative MPs as the first members of his new Cabinet.
George Osborne, MP for Tatton, will retain his role as Chancellor, and will also be the First Secretary of State - the ranking Cabinet Minister in the Government and the equivalent to Deputy Prime Minister.
The 43-year-old arrived at 10 Downing Street shortly after Mr Cameron had announced on his Twitter page that he was set to announce a number of Cabinet posts.
Mr Cameron wrote: "I have re-appointed George Osborne as Chancellor of the Exchequer. He will also be First Secretary of State - the ranking Cabinet Minister."
The appointment is a mark of the Prime Minister's appreciation of George Osborne's handling of the Treasury during the coalition and maintains continuity in the top two posts in Government held since 2010.
Theresa May also entered number 10 shortly afterwards, before Mr Cameron confirmed on Twitter that she had agreed to remain as Home Secretary.
Arriving back at the Home Office, she said: "We have achieved a lot over the last five years in the Home Office. But there is more to do and I am keen to get on and do it."
She added that the interception of communications would be a "key issue" for the Government after the so-called "snoopers' charter" was blocked by Lib Dem members in the Coalition.
Philip Hammond, 59, MP for Runnymede and Weybridge, was re-appointed to his role as Foreign Secretary.
He was appointed to the role in July last year when he replaced William Hague.
Mr Hammond said: "I'm delighted the Prime Minister has paid me the compliment of inviting me to be Foreign Secretary of the United Kingdom.
"I've set out before the election the big challenges I think the Foreign Office has to face over the coming years - the challenge of extremist, Islamist terrorism; the challenge of a resurgent Russia, ever more aggressive in its dealings with its neighbours; and the challenge of renegotiating our relationship with the European Union."
