David Cameron may have been forced to quit as prime minister following his EU referendum defeat - but he appears not to have lost his sense of humour.
Appearing in the Commons for the first time since the Brexit result, Cameron welcomed Labour's newly elected MP for Tooting, Rosena Allin-Khan, to parliament.
"I think I’d advise her to keep her mobile phone on, I think she might be in the shadow cabinet by the end of the day," he joked.
Jeremy Corbyn has lost 20 members of his shadow cabinet and several junior shadow ministers since the early hours of Sunday morning - as Labour MPs attempt to force him out.
Cameron added to laughter: "And I thought I was having a bad day."
Allin-Khan took the joke in good humour and grinned widely at the suggestion she may be called on to fill in a shadow ministerial job.
