David Cameron let out a cheery hum after handing the reins to Theresa May in a press conference outside number 10 Downing Street.
The PM formally announced that May would take over as PM following his final Prime Minister’s Questions on Wednesday.
Clearly worn out by the events of the past few weeks and overjoyed to be standing down, he let out a gleeful hymn on returning to number 10, unaware that he was still mic’d up!
Watch the hilarious video in full below:
Since this video was leaked a remix of his antics has appeared on social media.
It has even been turned it into a fantasy for cello and piano by composer Thomas Hewitt Jones.
A full orchestral version dubbed “Cemeron’s Lament in C Minor”.
And finally, a waltz.
