VETERANS involved in secret military research in Wiltshire in the 50s, have been invited back to see around the laboratories.

Many claim they were fooled into taking part in trials at Porton Down, which later damaged their health.

Former airman Douglas Shave of Poole, Dorset, believes the nerve gas tests he underwent in 1950 left him with severe eczema.

He was exposed to sarin, but experts at Porton have told him his skin complaints are unrelated.

In November 2004, an inquest into Ronald Maddison, who died 51 years ago during secret nerve gas tests, was held by Wiltshire coroner David Masters, who ruled that he was unlawfully killed.

Since then the High Court has ruled the government can challenge the inquest verdict.

RAF serviceman Ronald Maddison, from County Durham, died aged 20 after having sarin dabbed on his arm at the Porton Down facility.
