The Government yesterday condemned the behaviour of animal rights activists as the police confirmed that remains found on Cannock Chase were those of Gladys Hammond.

Leader of the House Geoff Hoon described the act as "nothing short of disgusting" after police said they were satisfied that the bones were those of the 82-year-old, whose body was stolen from a Staffordshire graveyard two years ago.

A Staffordshire Police Force spokeswoman said yesterday the body taken from the scene at Cannock Chase on Wednesday had been examined by a Home Office pathologist and had also undergone dental checks.

Further DNA tests are still being carried out to confirm identity although a police spokeswoman said detectives were satisfied that the body recovered was Gladys Hammond."

During questions on future business in the Commons, Tory MP Michael Fabricant (Lichfield), whose constituency includes the graveyard in Yoxall where her body was originally buried, condemned animal rights activists as "hypocrites in the extreme".

The desecration followed a long-running "terrorist" campaign against a guinea pig breeding farm co-owned by the late pensioner's son-in-law.

Mr Fabricant asked Mr Hoon to condemn those responsible for the "terrible deed" and others who "persecute" people who work in medical research.

He said: "These animal rights activists are hypocrites in the extreme because they will have had antibiotics and treatments and vaccinations against childhood diseases."

Mr Hoon replied: "I do agree with you, I think you put it very well. I think the behaviour of those responsible for this appalling incident was nothing short of disgusting and I think we all share the concern that the family affected have had."

David Hall and Partners, the owners of Darley Oaks Farm in Newchurch were carrying out "perfectly lawful activities that had been subject to so much attack and disruption", he added.

Those who have admitted taking part in the conspiracy to blackmail David Hall and Partners have been warned they are facing lengthy jail sentences.
