Robbie Williams is set to headline a one-off gig in support of the Help For Heroes charity.

The concert, at Twickenham Stadium in London on September 13, will also feature Alexandra Burke and Plan B.

Williams said: “I am honoured to be a part of this show and to help draw attention to the amazing job done by our servicemen and women throughout the world.

“Their dedication to our country is phenomenal and we are all so proud of them.”

Other acts on the bill include The Saturdays, Pixie Lott and James Blunt, while entertainers Bruce Forsyth, Jack Dee and Michael McIntyre will also appear.

All proceeds from the concert will go towards the Help For Heroes charity.

Tickets are due to go on sale on Wednesday (August 4) at 9am.
