British lawmakers have dealt Prime Minister Theresa May her second defeat in two days in battles over the government's plans for Brexit.
The House of Commons voted for a motion designed to prevent the government delaying key decisions as Brexit approaches on March 29. The measure says that if Parliament rejects the divorce deal May has agreed with the European Union, the government must come up with a "Plan B" within three days.
The government previously had 21 days to report back to Parliament.
Lawmakers are due to vote on May's deal on Tuesday, and look likely to reject it.
Opponents of the agreement suspect the government may try to run down the clock, to leave Parliament facing a last-minute choice between May's deal and a no-deal Brexit.
On Tuesday, lawmakers voted to put curbs on the government's ability to spend taxes on no-deal measures.
