Prince Harry's 30th birthday celebrations will begin tonight with a ''beer'' with Southampton-hero Dave Henson.

British Armed Forces captain Dave Henson, celebrates his 30th birthday tomorrow - the same day as the Prince reaches the same landmark.

The Games will be brought to a close tonight with a rock concert featuring acts like the Foo Fighters and Kaiser Chiefs in front of a sell-out crowd of 26,000.

The Prince and Mr Henson, a former Royal Engineers Captain from Southampton, have become firm friends during the build up to the international competition for wounded servicemen and women being held at London's former Olympic Park.

Dave, a former St George pupil from the Bitterne Park area of the city, was the captain of Team GB and won gold in the 200m sprint on the first day of the Invictus Games.

Harry, speaking during the weekend, which has seen thousands cheer on the competitors, said: ''On the birthday side of things, I'll be chuffed to bits when I'm having a beer with Dave Henson, captain of the GB team - we turn 30 at exactly the same time, on Sunday night.

''We're really looking forward to being 30, both feeling quite old about it.''

Speaking about the competitors he added: ''Rest assured these guys are going to party on Sunday night and they deserve to.''

It was rumoured that Harry was going to stage a Kensington Palace birthday party on Saturday night but yesterday, as planned, he stayed late into the evening watching Invictus events at the Queen Elizabeth Olympic Park.

The Invictus Games has proved to be a successful Paralympics-style championship, with full stands and competitors, many with missing limbs or other serious injuries, welcoming the opportunity to take on the sporting challenge.

Harry launched the contest earlier this year, after being inspired by a similar initiative in the US, and he hopes it will support competitors' rehabilitation and raise awareness of those injured serving their countries. It has become one of the most significant things he has done in his working life and for the past eight months he has been hands-on working behind the scenes.

The Prince said yesterday he was ''over the moon'' by how the Games had gone and suggested it could be staged next year outside of London.

He said: ''We've now got America showing interest in 2016 and Canada showing interest in 2017 so the question is what do we do next year?

''I personally, along with a couple of other people on the board, would love to keep it in the UK, maybe head north whether it be Glasgow, whether it be Sheffield, whether it be Manchester.''

The Vamps, Rizzle Kicks, James Blunt, Ellie Goulding, Ryan Adams and Military Wives Choirs are among the other acts to feature on the bill, with highlights to be screened by the BBC.
