Theresa May and Jeremy Corbyn have united to urge the public to download a Christmas charity single dedicated to the memory of Jo Cox.

The Prime Minister and the leader of the opposition championed the the cover of the Rolling Stones' You Can't Always Get What You Want, which will raise funds for the Jo Cox Foundation.

The single, which will be released on Friday, has been recorded by MP4, a singing group composed of MPs, Fife singer KT Tunstall and David Gray.

Cox, who was Labour MP for Batley and Spen, was shot and stabbed to death in Birstall, West Yorkshire, on June 16, one week before the EU referendum.

The foundation set up in her honour supports charities including the Royal Voluntary Service and White Helmets.

Speaking during Prime Minister's Questions, Labour leader Jeremy Corbyn asked: "Sadly our late colleague Jo Cox will not be celebrating Christmas this year with her family.

"She was murdered and taken from us so I hope the Prime Minister, and I'm sure she will, will join me in encouraging people to download the song which many members helped to create - a tribute to Jo's life and work and in everlasting memory of her."

Prime Minister Theresa May replied: "You are absolutely right to raise this issue. I'm sure everybody in this House wishes to send a very clear message - download this single for the Jo Cox Foundation.

"It's a very important cause and we all recognise that Jo Cox was a fine member of this House and would have carried on contributing significantly to this House and this country had she not been brutally murdered."

Chancellor Philip Hammond has announced the UK Government will make a charitable donation equivalent to the VAT payable on the sales of the single to the foundation.

May added: "I think everybody involved in it has in fact given their services for free."

MPs cheered as the PM referenced the parliamentary rock group MP4, noting: "I'm having a photograph with MP4 later this afternoon. And once again let's just encourage everybody to download this single."

In November, Thomas Mair was found guilty of the murder of Jo Cox and sentenced to a whole-life term in prison. Presiding judge Mr Justice Wilkie found that Muir, who shouted "Britain first" when he attacked the MP, was motivated by Nazism and white supremacy.
