TWO south Wiltshire mothers, falsely accused of killing their children, have set up a Foundation to prevent similar miscarriages of justice from happening again.

The Angela Cannings Foundation will also be a memorial to Sally Clark, the former Salisbury schoolgirl, who was also wrongly convicted of murdering her two baby sons and who tragically died a fortnight ago.

Former Salisbury mother, Angela Cannings, and south Wiltshire mum, Marianne Williams, were joined at the launch in London by Angela Gay from Worcestershire, who, with her husband, Ian, were eventually cleared of poisoning a three-year-old boy they hoped to adopt.

Angela and Sally were both imprisoned for murder before eventually being freed and cleared. Marianne was cleared last year at Winchester Crown Court of killing her 15-month-old son by salt poisoning.

Sally, 42, was found dead in her bed at her home in Hatfield Peverel near Chelmsford on March 16.

An inquest into her death has been opened and adjourned to a later date.

This week Angela, who left Salisbury to live in the west country, said the Angela Cannings Foundation would have two roles - to support other families in similar circumstances and lobby for changes in the controversial expert witness system used in such trials. Testimonies from expert witnesses have been blamed for several miscarriages of justice in cot death cases.

She added she had been persuaded to set up the Foundation after similar recent cases went to trial and were then thrown out.

She said: "When I was released it was made clear things were going to change in the system. But the Gays' and Marianne's case are recent and I am so incensed by the way the system in this country is not getting it right and are not listening to the families involved.

"Something should have been done a long time ago."

The Foundation will allow people who have gone through that system to help other families with the stress and trauma, and will help with financial assistance for appeals.
