David Cameron will leave Downing Street for the final time as PM later, with Theresa May waiting to replace him.
Mr Cameron has been taking part in his final Prime Minister’s Questions, before heading to Buckingham Palace to tender his resignation to the Queen.
He told MPs his time in power had been “amazing” and joked that apart from his royal audience his “diary for the rest of the afternoon is remarkably light”.
After taking office, Mrs May will set about naming her own frontbench team.
The current home secretary, 59, was the only remaining candidate in the Conservative leadership contest following Andrea Leadsom’s withdrawal on Monday.
The contest began when Mr Cameron, who has been prime minister since 2010, announced he would step down after losing the EU referendum in June.
During a generally light-hearted and jocular session of Prime Minister’s Questions, his 182nd as PM – Mr Cameron said he had answered 5,500 questions at the despatch box.
