Samantha Cameron has hailed the bravery of injured troops whom she met during a visit to an armed forces rehabilitation centre in Surrey.
The prime minister's wife said her recent visit to the Headley Court defence medical rehabilitation centre had been "awe-inspiring".
"Seeing some of the injuries and how soldiers overcome them is incredible," she told forces broadcaster BFBS.
"To see their optimism, their bravery is really quite uplifting."
The Surrey centre provides intensive medical treatment, psychological support and therapy to injured troops, many of whom have lost limbs in battle.
'Determination and bravery'
Mrs Cameron was talking about her work as a patron of the charity Tickets for Troops, which offers free tickets to art, music and sporting events for members of the armed forces.
She said she was delighted to be joined as a patron by Christina Schmid, whose husband Staff Sergeant Olaf Schmid died defusing a roadside bomb in Afghanistan last year.
Mrs Cameron said: "She's an inspiration to so many people - to us at the charity and to the troops and their families.
"It's incredible to see her determination and bravery. Over the last year or so what she's done to support families has really been incredible."
