Poisoned spy's widow denies he worked for MI6

The widow of poisoned former KGB agent Alexander Litvinenko says he was not working for British intelligence, as his alleged killer claims. Andrei Lugovoi, a former KGB man sought on a murder charge in Britain, said Thursday in Moscow that Litvinenko was working for MI6, the British foreign intelligence agency. "He will try everything to defend himself," Marina Litvinenko said in an interview with The Associated Press. British authorities are seeking Lugovoi's extradition to face trial in London, but Russian officials say their constitution bars extradition of Russian citizens.
