Soon to be former UK Prime Minister David Cameron has been caught quietly celebrating his new found freedom.
Mr Cameron was caught humming a jovial tune as he walked back into the iconic No.10 Downing St, moments after announcing a new prime minister will be in office by Wednesday (local time).
Mr Cameron was unaware his lapel microphone was still on. After humming a "doo doo doo doo," he closed door behind him and said "right... good". The cheerful ditty has since gone viral on social media.
Home Secretary Theresa May will be taking the United Kingdom's top job. Ms May says her priorities will be to administer Britain's exit from the European Union and to unite the country, creating a "strong, new, positive vision for the future".
