LONDON—Prime Minister Theresa May warned on Jan. 14 that Britain’s planned exit from the EU could be derailed, a last-ditch effort to win over Brexit-supporting lawmakers who have repeatedly said they will vote down her divorce deal.
The fate of the United Kingdom’s March 29 exit from the EU is deeply uncertain as parliament is likely to reject May’s deal on Jan. 15, opening up outcomes ranging from a disorderly divorce to reversing Brexit altogether.
