VAT on sales of the Christmas single in memory of murdered MP Jo Cox will be donated to charities which she supported, Chancellor Philip Hammond has announced.
The special recording of The Rolling Stones' hit You Can't Always Get What You Want features MPs from several parties alongside musicians including Kaiser Chiefs' frontman Ricky Wilson, Cockney Rebel's Steve Harley, KT Tunstall and David Gray.
Members of parliamentary rock group MP4 and the Royal Opera House Thurrock Community Chorus also feature on the track, which is due for release on Friday.
Money raised from the single will go to the Jo Cox Foundation, which supports a range of charities including the Royal Voluntary Service and White Helmets.
The Chancellor announced that the Government will make a charitable donation equivalent to the VAT payable on the sales of the single to the Foundation.
"Jo Cox dedicated so much of her life to helping people less fortunate than herself and the charity named in her honour is carrying on that excellent work," said Mr Hammond.
"It is only right that we do what we can to support that work and I am pleased to confirm that every single penny of sales from this single will go towards the good causes the Jo Cox Foundation supports."
