A woman who shared a desperate plea for a kidney on Facebook has undergone a lifesaving transplant after a stranger offered to be her donor.

Karen Davey, 41, had exhausted every avenue before turning to social media, where she said she did not "want to leave her family without a mother".

Gary Summerfield saw the mum-of-four's post and, after learning he was a match, donated one of his kidneys via an operation in July.

"I thought this lady needs one of my kidneys more than I need two of them," said Gary.

Karen's family said they would never be able to repay Gary for his generosity, adding that it had given her "another chance to be a mum".
