British Prime Minister Theresa May has conceded that lawmakers should have a retrospective debate — and possibly a vote — on her decision to take part in the bombing of Syria with the U.S. and France.

After she and Foreign Secretary Boris Johnson both said over the weekend that there was no need for such a vote, May's office said late Sunday that she would ask Speaker of the House of Commons John Bercow to agree to an emergency debate, to take place on Monday.

May will first defend her decision, in a statement to Parliament about 3.30 p.m., that will set out her reasons for supporting the bombing and take questions from lawmakers. If Bercow agrees — and it's unlikely he wouldn't — the debate will then follow.
