WATCH: The moment Truss resigns as prime minister
Liz Truss has resigned after six weeks in office.
Her speech was short and to the point. She says she cannot deliver the mandate on which she was elected.
She and the 1922 Committee chair agreed that there will be a new PM by next week.
Sir Graham Brady is set to lay out what happens next later today.
This will be the third new PM in a few months.
