An 83-year-old man has become the oldest person in the UK to donate a kidney while still being alive, the NHS Blood and Transplant service has said.

Nicholas Crace, from Overton in Hampshire, is also the oldest "altruistic" kidney donor - he will never meet the recipient of his organ.

He said: "It's nice to feel in old age that one can still be useful."

His surgeon said a kidney from a live donor "performs better, works quicker and lasts longer".
