Best Brexit outcome would be remain vote in a new referendum, says Luxembourg PM

Luxembourg Prime Minister Xavier Bettel put the chances of Britain's parliament passing the withdrawal deal at 50-50 and said the best possible Brexit outcome would be a new referendum and a vote to stay in the European Union.

Bettel spoke after EU leaders agreed to give British Prime Minister a reprieve to persuade lawmakers to back the withdrawal treaty she concluded with Brussels.

If she fails to do so, Britain will have until April 12 to offer a new plan or choose to quit without a treaty.

"The best possible outcome would be a new referendum and to stay," Bettel told reporters on Friday.
