Here is a list of the 59 MPs who have resigned or been sacked from the Government since Tuesday evening.
It is the equivalent of a third of the total “payroll vote” in the House of Commons – the number of MPs who hold positions from which they would have to resign in order to oppose the Government.
The 59 comprises six Cabinet ministers, 23 ministers, 22 parliamentary private secretaries, five trade envoys and three vice-chairs or deputy chairs of the Conservative party.
All departures are resignations unless otherwise stated.
