Watch: Cameron hums a merry ditty after quitting as British PM

Is David Cameron happy to have finally announced when he will be quitting as Britain’s prime minister?

Well, if this video clip is anything to go by, he’s overjoyed.

Seconds after announcing that he would be stepping down on Wednesday – with Theresa May set to take over – he retreated back towards the front door of 10, Downing Street.

Cameron, who had forgot to take off his microphone, then had a satisfied-sounding sing to himself, before, once inside, finishing with an assertive ‘right!’.
