A documentary broadcast on the BBC on January 22 said the attempt to poison Litvinenko may have been made on October 16 when Litvinenko met two Russian contacts at the same London sushi bar where he fell sick two weeks later.
Litvinenko, a Kremlin critic, died on November 23. On his deathbed, he blamed Russian President Vladimir Putin of ordering his killing. The Kremlin denies any involvement.

Meanwhile, the British "Times" newspaper reported last week that British police had a photo taken by a security camera of the man suspected of being Litvinenko's killer.
Scotland Yard refuses to discuss its ongoing investigation into Litvinenko's death.

A lawyer for Berezovsky on January 22 said the investigation had been suspended due to difficulties in investigating a refugee. Russian prosecutors have charged Berezovsky, who lives in London, with seeking to forcefully grab power.
They are also seeking to question Berezovsky as part of their own investigation into the Litvinenko poisoning
