Under-fire Jeremy Corbyn has defended not singing the national anthem at a Battle of Britain commemoration service yesterday.

The Labour leader was criticised by some, including in his own party, for remaining silent during God Save The Queen at St Paul's Cathedral in London.

Mr Corbyn told Sky News he had "stood in respect" throughout the ceremony marking the 75th anniversary of the Battle of Britain, as he thought about his parents who were air raid wardens during the Blitz.

When asked if he would sing the national anthem in the future, Mr Corbyn said: "I'm going to be at many events and I'll take part fully in those events.

"I don't see a problem like this."

He added: "The issue surely is we had a memorial for the Battle of Britain. I was there, I showed respect for it and I'll show respect in the proper way at all future events. That is what I will be doing.

"The proper way is to take a full part in them and I will take a full part in them."

A Labour source later told Sky News that Mr Corbyn would be singing the national anthem at future events.

The veteran left-winger is preparing to face David Cameron at the despatch box in his first Prime Minister's Questions.

He had invited supporters to tell him what they would like him to ask Mr Cameron - a request which drew 33,000 responses from the public.

He has had to choose just six to put to Cameron across the dispatch box.
