An exchange of letters between the U.K. Prime Minister Theresa May and Europe's top two lawmakers looks to have done little to improve the chances of her Brexit deal being passed in the U.K. Parliament.
May has placed a motion before lawmakers in the lower house of parliament, asking them to rubber stamp her withdrawal and future relationship agreement with the European Union. The vote is scheduled to take place on Tuesday at some point between 8 p.m. and 9 p.m. London time.
The government is forecast to lose the vote, with the main sticking point for some being the Northern Irish "backstop" which has been written into the withdrawal agreement.
This acts as a safety net to prevent any hard border with the Republic of Ireland, which is remaining as an EU member country. But many of May's critics see this provision as a way in which Britain could possibly be tied to the European Union indefinitely.
