Britain's Prince Harry has teamed up with his cousin-in-law Mike Tindall to support his charity campaign.
The 27-year-old royal is lending a helping hand to the 33-year-old rugby player's new aid organisation, Rugby For Heroes, which fundraises and mentors military men and women through playing the sport, and he is "delighted" to be helping the campaign.
Harry said: "As a serving member of Her Majesty's Forces and an avid rugby fan, I am delighted to hear about the valuable work of Rugby for Heroes.
"The military and rugby share distinctive core values - leadership, respect, courage and camaraderie - which is why the rugby community can play such an important role in supporting our armed servicemen and women to make the successful transition to civilian life."
Mike added: "We are truly honoured and delighted to have Prince Harry supporting the work of Rugby For Heroes."
The charity was first started by the 33-year-old England international and his former Gloucester Rugby Club teammates Ryan Lamb and Anthony Allen, who set up a buddy-style system for service personnel and rugby players, as well as providing summer camps for military families.
Harry and Mike - who became newest member of the royal family when he tied the knot to the prince's cousin Zara Phillips last July - are thought to enjoy "lots of banter" together and think of each other "a bit like a big and little brother".
A source added to the Daily Mirror newspaper: "Harry and Mike have always got on really well, they enjoy a laugh and joke together and have a rough-and-tumble relationship a bit like a big and little brother.
"It's daunting entering the royal family, but the younger royals in particular have always put Mike at ease and he has a particularly relaxed relationship with Harry - there's lots of banter between them.
"He and Harry have had a few conversations about Mike's work on Rugby For Heroes and Harry told him he was keen to help."
