Bromsgrove MP and Home Secretary, Sajid Javid, has officially announced his bid to become the next Prime Minister.
He tweeted: "I'm standing to be the next leader of Conservatives & Prime Minister of our great country.
"We need to restore trust, bring unity and create new opportunities across the UK. First and foremost, we must deliver Brexit."
It comes after Theresa May announced she will resign as Conservative leader on June 7 and in doing so, set off the official starting pistol on the race for the next prime minister.
In a magazine interview in December, Mr Javid sought to signal his leadership ambitions by arguing that he wanted the Tories to be the party of social mobility.
Javid, 49, backed Remain in the referendum but has since positioned himself as a firm Leaver.
He became the first home secretary from an ethnic minority background when he was appointed in April 2018.
The son of a Pakistani bus driver from Rochdale, he was a managing director at Deutsche Bank before becoming MP from Bromsgrove in 2010.
