Theresa May has announced her resignation as prime minister and Conservative party leader.
In an emotional statement on Downing Street alongside her staff and husband Philip, the prime minister said she would step down as leader on Friday June 7 but remain in post as prime minister until a successor has been chosen by the party.
May said she had decided to step down in order to allow a successor to implement Brexit, having failed three times to pass her deal with the European Union through parliament.
"I have done everything I can to convince MPs to back that deal," she said.
"I believe it was right to persevere even when the odds against success seemed high. It is now clear to me it is in the best interests of the country for a new prime minister to lead that effort."
She added: "I will resign as leader of the Conservative and Unionist Party on Friday June 7."
May's announcement followed a meeting on Friday morning with the Chair of the 1922 Committee of Conservative MPs, Sir Graham Brady.
The committee's executive met on Wednesday to vote on whether to change Conservative party rules in order to allow a vote of no confidence in May, with the result sealed in an envelope until she confirmed whether she would resign.
The announcement also comes ahead of the results of the European Parliament elections in which May's Tory party is predicted to come as low as fifth place.
