Source-derived summary

Alexander Valterovich Litvinenko was an officer of the Russian Federal Security Service (FSB) and its Soviet predecessor, the Committee for State Security (KGB), until he left the service and fled the country in late 2000, defecting to the UK.

In 1998, Litvinenko and several other Russian intelligence officers said they had been ordered to kill Boris Berezovsky, a Russian businessman. After that, the Russian government began to persecute Litvinenko. He fled to the UK, where he criticised the Russian President Vladimir Putin and the Russian government. In exile, Litvinenko worked with British and Spanish intelligence, sharing information about the Russian mafia in Europe and its connections with the Russian government.

On 1 November 2006, Litvinenko was poisoned and later hospitalised. He died on 23 November, becoming the first confirmed victim of lethal polonium-210-induced acute radiation syndrome. Litvinenko's allegations about misdeeds of the FSB and his public deathbed accusations that Putin was behind his poisoning resulted in worldwide media coverage.

Subsequent investigations by British authorities into the circumstances of Litvinenko's death led to serious diplomatic difficulties between the British and Russian governments. In September 2021, the European Court of Human Rights (ECHR) ruled that Russia was responsible for the assassination of Litvinenko and ordered Russia to pay Litvinenko's wife €100,000 in damages plus €22,500 in costs.

The ECHR found beyond reasonable doubt that Andrey Lugovoy and Dmitry Kovtun killed Litvinenko.

Editorial analysis

Why this record matters

The phrase “2006 fatal poisoning of a former FSB and KGB officer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q2395283. Authority coordinates are 51.511, -0.151. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2000, 1998, 2006 and 2021.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
