Members of the public stand outside the gates of Downing Street

Boris Johnson bounded out of Number 10 to the loud applause of his remaining supporters as the tune of “Bye, Bye Baby” blasted out from beyond the Downing Street gates.

Brooding grey clouds had blotted out the sun over central London as Mr Johnson, dubbed the “greased piglet” for his previous ability to slip out of politically perilous situations, faced the glare of the world’s media at 12.30pm.
