Tea laced with polonium
Alexander Litvinenko, a Russian dissident and former KGB agent, was poisoned by radioactive polonium–210 while drinking tea during a meeting with former security colleagues at the Millennium Hotel in Grosvenor Square in 2006. He died three weeks later in a London hospital. Litvinenko, who was granted asylum in Britain in 2000, was working for MI6 prior to his death, his inquest was told. The British government believes the Russian state was involved, but no one has ever been charged. Picture: PA
