Baby Kayleigh Valentine died at Alder Hey

Her organs were returned to the Valentines last year and a second funeral was held.

But, following this latest revelation, Janet Valentine says the family is devastated and faces the prospect of having to hold a third funeral.

"We have another funeral to come, but as Kayleigh's mother, I want to do the best by her," she said.

"If they had told us all of this 12 months ago, I could have gotten on with my life."

The hospital has confirmed brain tissue was given to a student at Liverpool University conducting research into low birth weight babies and said it is now trying to contact all involved families.

Last year Alder Hey confirmed that between 1988 and 1995, a total of 850 organs were stored at Liverpool University, by the then head of their post-mortem team, Professor Dick van Velzen.

New guidelines have since been published by the Royal College of Pathologists to give parents more say.

But families are still calling for changes in the law.
