Former England football captain David Beckham has announced that he will be taking on a role as Invictus Games Ambassador.
In a post on his personal Instagram page, he said:
"I’ve been lucky enough to meet and work with many serving, veteran and wounded British armed forces personnel over the years and I’ve been humbled by the courage, resilience and spirit shown by each and every one of them.
"So, I’m incredibly proud to announce I will be an Ambassador for this year’s Invictus Games in Sydney," he wrote.
"The entire Invictus Games team, led by the Duke of Sussex, has achieved remarkable things in such a short space of time, using sport as a powerful force to rehabilitate and unite and I can’t wait to be part of the energy and the excellence of the Games this year."
The UK team that will be competing in Australia was officially announced in May.
The Invictus Games were founded by Prince Harry following a 2013 visit to the USA Warrior Games.

There, he saw the way in which sport can help those suffering from physical and psychological illnesses, and was inspired to create the Invictus Games.
Previous Invictus ambassadors include actor and comedian Mike Myers, and classical singer Katherine Jenkins.
The fifth Invictus Games in May 2020 will be staged in the Hague in the Netherlands.
