Litvinenko inquest: Evidence decision raises doubts
The widow of the poisoned spy Alexander Litvinenko says she is "utterly dismayed" by the decision not to make public evidence that may point to the Russian government.
The government had asked for certain material to be excluded from a public hearing on the grounds of national security, which includes evidence on the Russian state and whether or not British security and intelligence services could have prevented Mr Litvinenko's death.
The coroner is instead seeking advice on holding a form of public inquiry instead, during which evidence about Russia's role in the killing could be heard in secret.
