LONDON, March 27 (Xinhua) -- Theresa May on Wednesday agreed to step down as British Prime Minister after Brexit deal is delivered.

She made the statement when addressing the 1922 Committee, the Conservatives' parliamentary group in the House of Commons.

"I know there is a desire for a new approach -- and new leadership -- in the second phase of the Brexit negotiations -- and I won't stand in the way of that," she said.

"But we need to get the deal through and deliver Brexit," she added.

"I am prepared to leave this job earlier than I intended in order to do what is right for our country and our party," May told her fellow MPs.

She urged the committee to back the deal to "complete the historic duty", according to a statement from the prime minister's office.

The latest development came before MPs are set to vote on changing the Brexit date in UK law from March 29 and also vote on eight possible Brexit options in the indicative votes.
