Help! Beatles quips abound as PM mocks Corbyn's nuclear stance
David Cameron and Tory MPs used some of The Beatles' biggest hits to mock Jeremy Corbyn's suggestion that the UK could retain its nuclear missile submarines but send them to sea without their warheads.
Mr Corbyn made the suggestion on BBC One's The Andrew Marr Show as he reiterated his long-standing opposition to nuclear weapons.
But the idea was seized upon by the Tory MP for Lincoln, Karl McCartney, during Prime Minister's Questions.
He said: "Do you agree with me that our nuclear deterrent only works against our nation's enemies if our nuclear submarines are actually equipped with nuclear missiles?
"And that those such as the Leader of the Opposition who do not believe this have a defence policy inspired by The Beatles' Yellow Submarine and shows that while the members opposite may Twist And Shout, their current leader certainly needs Help."
Mr Cameron congratulated Mr McCartney on his "ingenious question" before deploying his own Beatles-inspired joke.
He said: "There is a comic element to sending submarines to sea without missiles in, but in fact it is absolutely serious because the deterrent has been, on a cross-party basis, an absolutely key part of our defence and making sure we have got the ultimate insurance policy, which we support on this side and we should vote on in this House.
"All I can say when it comes to Beatles songs, I suspect that the Leader of the Opposition prefers Back In The U.S.S.R."
