Watch: PM's innuendo-laced response met with howls of laughter
Theresa May left MPs howling with laughter after an innuendo-laced response to a Tory celebrating his birthday.
Peter Bone urged the Prime Minister to deliver him another birthday present by agreeing to reopen Wellingborough prison in his constituency, adding: "Or would you rather just sing happy birthday?"
Mrs May replied: "I'm very happy to wish you a very happy birthday today, many happy returns.
"I hope that Mrs Bone is going to treat the occasion in an appropriate manner."
Mrs May paused as MPs started laughing.
Commons Speaker John Bercow, intervening, joked: "Order! I want to hear what's coming next."
Mrs May replied: "Calm down, Mr Speaker."
She is the latest Prime Minister to fall victim to a "Mrs Bone" moment in the Commons.
In 2011, David Cameron joked to Mr Bone: "I feel that a very big part of my life is spent trying to give pleasure to Mrs Bone. On this occasion, I can go only so far."
Mr Bone (64), had asked about a potential Greek bailout and referenced his wife Jennie - something he often does when asking questions in the Commons.
