LONDON - British prosecutors may soon be asked to bring charges against a Russian businessman in the radiation poisoning death of a former Russian intelligence agent.
The Guardian quotes unidentified sources in government, who say suspicion had fallen on Andrei Lugovoi, who met Andrei Litvinenko the day he believed he was poisoned.
Litvinenko died three weeks later from exposure to the rare radioactive isotope polonium-210.
Metropolitan Police aren't commenting on The Guardian's report, except to say that the investigation was continuing.
The Guardian quoted Lugovoi as saying in Moscow: "I am not guilty. I have nothing to do with the killing of Litvinenko.''
In a deathbed statement last November, the agent-turned-Kremlin-critic accused President Vladimir Putin of ordering his murder.
But the Kremlin has dismissed the allegations.
