Liz Truss has announced that she is to resign as prime minister just six weeks after taking office.
The dramatic announcement outside the door to 10 Downing Street came shortly after the PM requested a meeting with the chair of the backbench 1922 Committee, Sir Graham Brady.
An election for the leadership of the Conservative party will be completed by 28 October and Ms Truss will remain as prime minister until a new leader is chosen.
Sir Graham, who oversees leadership elections, said it was his expectation that Conservative party members will get the final vote on the new leader unless MPs coalesce behind a single candidate for a coronation.
The breakneck timetable would require any ballot to be conducted online in a matter of a day or two.
