After her Brexit plan went down to the most resounding defeat in modern British history, Prime Minister Theresa May was told to come back with a Plan B.

She did that Monday.

But her Plan B looked a lot like Plan A, setting the stage for another battle royale with rebellious British lawmakers over Brexit, or the process of withdrawing Britain from the European Union.

Even though her plan was defeated in Parliament last week by 230 votes, Mrs. May told lawmakers on Monday that she still hoped to win them over by negotiating changes to the plan that many regard as cosmetic.

She told lawmakers that she could not rule out the possibility of leaving the European Union without any agreement, even though preventing that outcome is probably the one thing that a healthy majority in Parliament can agree on as a course of action.
