Extract from the Telegraph:
"A mother in need of a kidney transplant was denied her daughter's "perfect match" organs after her sudden death.
Laura Ashworth died, aged 21, at Bradford Royal Infirmary after a suspected asthma attack.
She had spoken of her desire to help her mother, Rachel Leake, who has kidney failure, but despite being on the national organ donor register, did not formally record her wish for her mother to benefit.
A transplant co-ordinator then told Miss Leake, 39, that her only child's organs would go to strangers.
One of Laura's kidneys went to a man in Sheffield and the second to a man in London. Her liver was given to a 15-year-old girl."
