Most leaders will leave office devastated, but seconds after David Cameron finished telling reporters of his plans to step down from office last month, he walked back through the door of his Downing Street residence and the live microphone he was still wearing caught him in an unguarded musical moment, BBC reports.

According to a clip from Daniel Sandford, the British Prime Minister sang to himself "Do doooooooo, do doooo"...

And anyone can easily ascertain that the British Prime minister had resigned a happy man.

David announced his resignation last month because he supported the losing side in the referendum for Britain to leave the European Union. He had said the choice of the people will be respected when he announced his intention to resign after the results.

In announcing his resignation, David Cameron said "The country needs a new leadership" , but also added that he would remain in office until October 2016 to ensure that Britain transitions smoothly into her new state as an independent and EU-free country.

UK slammed the door on the European Union at the end of a Thursday evening referendum with 51.9% of votes (17,410,742) in favor of leaving the EU.

The historic Brexit vote has seen some dim consequences for Britain despite having been cast just hours ago.

The surprise result will rattle Europe and shape the nation’s place in the world for years to come.
