The British government says it will change the rules on the cremation of organs from people who've died, following criticism of post mortem procedures at a children's hospital in Liverpool.

It has emerged that doctors at the Alder Hey hospital have continued removing tissue samples from dead children without their parents' consent, despite assurances given last year when details of the practice were first publicised.

The hospital, which is currently under investigation over the issue, has said it will seek the assistance of parents to draw up clearly worded consent forms.
