David Cameron has insisted he will not resign if Britain votes to leave the European Union in the forthcoming referendum.
Challenged at Prime Minister's Questions by Labour MP Richard Burgon whether he would quit in the event of an "out" vote, Mr Cameron replied simply: "No."
Conservative MPs on both sides of the Brexit debate have insisted publicly that Mr Cameron will carry on in No 10 regardless of the outcome of the referendum on June 23.
However many at Westminster believe that if the public rejects his EU reform package and votes to leave, he will be too badly damaged politically to carry on and will be forced to go.
