LONDON (Reuters) - British Prime Minister Theresa May will hold a conference call with ministers on Sunday to discuss Brexit, a government source said.

May returns to parliament on Monday to make a statement on how she will proceed with Britain’s departure from the European Union after her deal was defeated by lawmakers last week.
