Theresa May defies Tory rebels to press on with Brexit deal

Prime minister to insist her deal would allow the UK to control immigration

Theresa May will move to seize back the initiative from mutinous Tory MPs on Monday by promoting her Brexit deal with a defiant speech to business leaders, even as critics in Westminster scramble to trigger a no-confidence vote in her leadership.

As she enters perhaps the most perilous week of her premiership, May will insist at the CBI annual conference in London that her deal delivers on the central demand of voters in the 2016 referendum, by allowing the UK to control immigration.
