Outgoing British Prime Minister David Cameron has signed off his final questions session in Westminster telling MPs: "Nothing is impossible. I was the future once."

The words to mark the end of his six-year premiership brought Conservative MPs to their feet.

But the Labour front benches and SNP refused to stand - and repay Mr Cameron who encouraged Tory MPs to get up when Tony Blair left office.

Mr Cameron brought a rowdy, mainly good humoured and at times funny session to an end by paying tribute to all MPs for their work.

And, watched by his wife and children in London's House of Commons, he said: "Nothing is really impossible if you put your mind to it, after all I was the future once."

It was a packed 38-minute session during which Mr Cameron compared UK Labour leader Jeremy Corbyn to Monty Python's Black Knight and produced photographic proof that he loved Larry the Downing Street cat, adding: "Sadly, I can't take it with me."

He produced a picture of him in an armchair with the cat on his lap as proof - and later posted the photograph on Twitter.

In return, Mr Corbyn thanked Mr Cameron's mother for her fashion advice - Mr Cameron had previously given the Labour leader a dressing down telling him his mother would say he should straighten his tie.

And made a gag about "unscrupulous bosses".

Even on his way out of the door, Mr Cameron - who told MPs he had addressed 5,500 questions in his six years - did not miss the chance to make the most of Labour's troubles.

But he paid some tribute to Mr Corbyn telling him he admired his tenacity in holding on.

The SNP refused to be drawn into the merriment - the party leader in the House of Commons said his benches would not applaud the man who took Scotland out of the EU.

In handing over to Theresa May, who sat on his left and said little, Mr Cameron told Labour it was 2-0 to his party on women Prime Ministers - and that with "not a pink bus in sight".

But his serious message to the woman who will take over from him by the end of the day was that it was vital for the UK to get access to the EU single market.
