A 12-year-old boy has finally come face-to-face with a stranger who saved his life by donating his kidney.
Tom Higgs is the first person at Great Ormond Street Hospital to receive a kidney from a living donor.
Tom met his donor, Roger Sutton, who is a 53-year-old GP, after the pair exchanged letters through their transplant co-ordinators.
Tom suffers from a rare type of kidney disease since he was five and has been on the donor list since he was eight.
Tom's mum Vicky said: "Our lives have changed so much, it's hard to believe. When we heard about the match, we were told that the organ was from a living donor who had decided to donate a kidney to a stranger. We were really surprised that someone would be so selfless."
