Summary
Alexander Litvinenko, a former officer of Russia’s Federal Security Service (FSB) who had defected to the United Kingdom and become a British citizen, was fatally poisoned with the radioactive isotope polonium-210 in London in November 2006. He fell ill on 1 November 2006, shortly after drinking green tea at the Pine Bar of the Millennium Hotel in Grosvenor Square with two former Russian intelligence officers, Andrey Lugovoy and Dmitry Kovtun. After three weeks of decline from acute radiation syndrome, he died on 23 November 2006 at University College Hospital, aged 44. He is regarded as the first confirmed victim of polonium-210–induced acute radiation syndrome. The killing, carried out with a rare nuclear material that left a radioactive contamination trail across London, became one of the most notorious international incidents of 2006 and a defining episode in post–Cold War relations between Russia and the West. A UK public inquiry concluded in 2016 that the assassination was probably ordered by the FSB and “probably approved” by President Vladimir Putin—a finding Russia rejected.
Background
Alexander Litvinenko was born on 30 August 1962 in Voronezh, in the Russian SFSR. He served in the KGB from the late 1980s and, after the Soviet collapse, became an FSB officer specialising in the investigation of organised crime. In November 1998 he and several colleagues held a press conference alleging that senior FSB officers had ordered him to assassinate the exiled oligarch Boris Berezovsky—an extraordinary public accusation against Russia’s security establishment that led to his prosecution and dismissal.
Litvinenko fled Russia in October 2000 and reached the United Kingdom, where he was granted political asylum on 14 May 2001. In London he worked as a writer and consultant, associating with Berezovsky and Chechen émigré circles and cooperating at times with British intelligence. He co-authored Blowing Up Russia: Terror from Within, which alleged that the FSB had staged the 1999 Russian apartment bombings to help bring Putin to power. He became a naturalised British citizen in October 2006, only weeks before his poisoning.
The Poisoning
On the afternoon of 1 November 2006, Litvinenko met Lugovoy and Kovtun at the Pine Bar of the Millennium Hotel in Grosvenor Square, central London. Investigators later concluded that polonium-210 had been introduced into a pot of green tea he drank there. He fell violently ill that evening and was hospitalised, at first with an undiagnosed condition; only in his final days did testing identify the cause as poisoning by polonium-210, an intensely radioactive alpha-emitting isotope almost impossible to detect by ordinary means and lethal in microscopic quantities when ingested.
Litvinenko died on 23 November 2006. In a statement dictated shortly before his death, he directly accused Vladimir Putin, declaring that “you may succeed in silencing me but that silence comes at a price,” and that the “howl of protest from around the world will reverberate … in your ears for the rest of your life.”
The Polonium Trail
Because polonium-210 is a distinctive and traceable material, its use turned London into the scene of an unprecedented radiological investigation. Health authorities detected polonium contamination at the Millennium Hotel, offices, restaurants, and other sites Litvinenko and the suspects had visited, as well as on aircraft that had flown between London and Moscow. The UK Health Protection Agency monitored thousands of people for possible exposure. The episode was the first known instance of polonium-210 being used as a murder weapon, raising alarm about the availability of nuclear material and the possibility of state involvement, since the isotope is produced in significant quantities only in nuclear reactors.
Investigation and Inquiry
A British murder investigation named Andrey Lugovoy, a former officer of Russia’s Federal Protective Service, as the principal suspect, and later Dmitry Kovtun as a second suspect. The United Kingdom formally requested Lugovoy’s extradition on 28 May 2007, but Russia refused, citing the constitutional prohibition on extraditing its own citizens; Lugovoy went on to become a member of the Russian State Duma.
After years of legal proceedings, a UK public inquiry chaired by Sir Robert Owen published its report in January 2016. It concluded that Lugovoy and Kovtun had poisoned Litvinenko and that the operation was probably directed by the FSB under its director Nikolai Patrushev and “probably approved” by President Vladimir Putin. In September 2021, the European Court of Human Rights ruled that Russia was responsible for the assassination, finding beyond reasonable doubt that Lugovoy and Kovtun had carried out the killing. Russia denied any involvement throughout.
Significance
The poisoning of Alexander Litvinenko was among the most consequential political killings of 2006, and its reverberations extended far beyond that year. The use of polonium-210 to murder a British citizen on the streets of London marked an alarming new form of transnational assassination, blurring the line between conventional espionage and the use of nuclear materials, and it severely strained UK–Russia relations, leading to reciprocal expulsions of diplomats. The case established a template that later informed responses to further attacks on Russian émigrés and defectors in Britain, most notably the 2018 Salisbury nerve-agent poisoning of Sergei Skripal. Occurring in the same year as North Korea’s first nuclear test and the intensifying Iran nuclear crisis, it underscored 2006 as a year in which anxieties about nuclear and radiological materials moved to the centre of international security, while its unresolved accountability—Russia’s refusal to extradite the suspects—became an enduring emblem of the limits of international justice.
