Sussex professor explains downfall of poisoners

A Sussex professor who was a key witness in the report into the murder of ex-Russian Spy Alexander Litvinenko has told ITV Meridian that committing the crime in the UK was the poisoners' downfall.

Mr Litvinenko died eight years ago when he drank a cup of tea laced with the radioactive substance. Pulonium. The men who met him have been named but remain in Russia.

Fred spoke to Professor Norman Dombey who said that 'almost anywhere else on Earth' Litvinenko's death would have been merely suspicious.
