The Latest: May vows to contest leadership challenge

LONDON (AP) — The Latest on political turmoil in Britain (all times local):

8:50 a.m.

U.K. leader Theresa May is vowing to fight a no-confidence vote “with everything I’ve got,” appealing to party colleagues to support her leadership.

The announcement of the challenge to May’s leadership throws Britain’s already rocky path out of the European Union, which it is due to leave in March, into further chaos.  

Many Tory lawmakers have been growing angry with May over her handling of Brexit, and the challenge comes days after she postponed a vote to approve a divorce deal with the EU to avoid all but certain defeat. 

If she loses Wednesday’s vote, May must step down and there will be a contest to choose a new leader. She will remain leader, and prime minister, until the successor is picked. If she wins, she can’t be challenged again for a year.
