U.K. Prime Minister Theresa May has told Conservative Party lawmakers that she will quit once the country has left the European Union — but she didn't set a date. 

Conservative lawmaker James Cartlidge told reporters as he left the 1922 Committee of Conservative lawmakers that May told the gathering "she would not remain in post for the next phase of the negotiations."

Those will deal with Britain's future relationship with the EU.

Britain was due to leave the EU on March 29 but May has got a short delay after her divorce deal with the EU was rejected overwhelmingly by lawmakers on two occasions.

Britain's Brexit Secretary Stephen Barclay has put down a motion to have Parliament sit on Friday — the clearest sign yet the government plans to bring Theresa May's European Union divorce deal back for a third vote.

Lawmakers in the House of Commons can sit on Fridays if they agree to do so.

He says "while I appreciate it may cause some inconvenience, I hope all members would agree that it's better to have it and to not need it, than to need it and not have it." 

But it remains unclear whether the measure will be proposed. Commons Speaker John Bercow said Wednesday he would not accept another vote on the twice-rejected deal unless substantial changes were made.

British lawmakers will get to vote on eight widely differing options for the U.K.'s departure from the European Union.

House of Commons Speaker John Bercow selected the motions on Wednesday from 16 proposals submitted by lawmakers.

The ones to be considered include calls to leave the EU without a withdrawal deal, to stay in the EU's customs union and single market, to put any EU divorce deal to a public referendum, and to cancel Brexit if the prospect of a no-deal Brexit gets close.

The "indicative votes" are intended to reveal if any kind of Brexit plan can command a majority in Parliament. Lawmakers have twice rejected Prime Minister Theresa May's Brexit deal with the bloc.

The government has promised to consider the outcome of the votes, but not to be bound by them.
