May was meeting the head of the governing party committee in charge of leadership elections to agree a timetable to stand down and allow a successor to be chosen, the reports said.

The leader of the party automatically becomes the prime minister.

Multiple reports said she intended to resign as head of the party on June 10 but continue as caretaker prime minister until the party elects a new leader.

The humiliating spectacle of May, who will become one of Britain's shortest-serving post-WWII prime ministers, detailing her own departure date follows a fresh revolt to her latest Brexit plan this week among cabinet colleagues and Tory MPs.

The embattled leader has previously said she would step aside once her unpopular EU divorce deal had been passed by parliament, and launched a fresh bid Tuesday for lawmakers to approve it in early June.

The government has now postponed that vote.

MPs have already overwhelmingly rejected her withdrawal agreement, struck with European Union leaders last year, three times.

May's latest proposals, which included giving them the option of holding a referendum on the deal, prompted a furious reaction from Conservatives -- including cabinet members.

"I thought she deserved one last roll of the dice. But she took those dice and threw them off the table," a senior minister told The Times.
