David Cameron will be leaving 10 Downing Street on Wednesday - nine weeks earlier than planned after another breathtaking day in Westminster saw the Tory leadership contest cut short.
He set out the timetable for handing over the No 10 keys to Theresa May, who was announced the new Tory leader after her rival Andrea Leadsom pulled out of the race.
Bizarrely, the outgoing Prime Minister was then caught on microphone humming a tune as he walked back into Number 10.
There is disagreement over what tune he was, with some suggesting it was the theme tune to American political TV drama The West Wing and others saying it was from Winnie-the-Pooh.
It capped another strange day in Westminster politics, with Mrs May launching the second phase of her leadership campaign just an hour before Mrs Leadsom conceded.
Today's fast-paced developments means Mr Cameron's swansong to his premiership is brutally cut short and his wife Samantha and three children Nancy, Arthur and Florence will have to start packing their bags tonight to make way for Mrs May and her husband Philip on Wednesday.
