May to write to EU's Tusk on Brexit extension Tuesday or Wednesday - spokesman

LONDON (Reuters) - British Prime Minister Theresa May will write to European Council President Donald Tusk to request a delay to Brexit either on Tuesday or Wednesday, her spokesman said.

May's team of top ministers discussed Brexit for 90 minutes on Tuesday, the spokesman said, including the implications of a ruling by parliament's Speaker on Monday that May could not bring her Brexit deal back for a third vote unless it was fundamentally changed.

May had hoped to win last minute approval for her deal ahead of an EU summit on Thursday at which a delay is expected to be discussed by EU leaders.
