Litvinenko: Call for inquiry into Russian spy death

The widow of the former Russian spy Alexander Litvinenko has called for the upcoming inquest into his death to be abandoned and replaced with a public inquiry.

Marina Litvinenko said it was the only way to establish the truth about the death of her husband, who was poisoned with radioactive polonium in London in 2006.

The coroner has ruled that the inquest could not take evidence on possible Russian state involvement, citing national security.
