Alexander Litvinenko Polonium-210 Poisoning (London, Nov 2006)
Introduction
Alexander Litvinenko was a former officer of Russia's Federal Security Service (FSB) who defected to the United Kingdom and became a fierce critic of Vladimir Putin and the FSB. On 1 November 2006 he met with former FSB colleagues Andrey Lugovoy and Dmitry Kovtun at the Pine Bar of the Millennium Hotel in London. Within hours he was gravely ill. Doctors initially struggled to identify the cause; it was eventually determined he had been poisoned with polonium-210, a highly radioactive substance not ordinarily available outside state nuclear programmes. Litvinenko died on 23 November 2006, aged 43.
The Polonium Trail
The unique signature of Po-210 — highly radioactive but emitting only alpha particles, invisible to standard radiation detectors — made it both an effective assassination tool and an inadvertent trail. UK investigators traced the polonium across London through multiple locations: the Pine Bar of the Millennium Hotel where Litvinenko met his contacts, the Itsu sushi restaurant where an earlier meeting had taken place, the Emirates Stadium where Lugovoy had attended a football match, and on aircraft between London and Moscow. The contamination trail provided forensic evidence of the route the poison had taken and the individuals who had carried it.
The Owen Inquiry
The UK public inquiry chaired by Sir Robert Owen published its findings in January 2016. The inquiry concluded that Lugovoy and Kovtun had administered the polonium-210 to Litvinenko, probably at the Pine Bar meeting on 1 November 2006. The inquiry further found that the FSB operation to kill Litvinenko was "probably approved" by then-FSB Director Nikolai Patrushev and by President Vladimir Putin. The standard of proof applied was the civil standard — balance of probabilities — rather than the criminal standard, and the inquiry was explicit that it could not make findings of criminal guilt.
Russia's Response
Russia categorically denied any involvement, describing the inquiry as politically motivated. Lugovoy, who was elected to the Russian State Duma (parliament) in 2007 — a position conferring immunity from prosecution — gave media interviews in which he denied any role in Litvinenko's death and offered alternative theories. Russia refused extradition requests from the UK. Kovtun has similarly denied involvement. No criminal prosecution in either Russia or the UK has resulted in convictions, though Lugovoy and Kovtun remain the named suspects in the UK Metropolitan Police investigation.
Why Polonium-210
The choice of Po-210 carries specific implications. Its production requires access to nuclear reactors; the specific isotope is produced in significant quantities only in state nuclear facilities, of which Russia has several. Commercial sources are negligible. The use of Po-210 as an assassination weapon is consistent with a state-level operation with access to nuclear materials and is inconsistent with a private criminal operation. This inference from the weapon itself substantially shaped the Owen Inquiry's conclusion about state authorisation.
Litvinenko's Own Accusation
In a statement dictated from his hospital deathbed and released after his death, Litvinenko directly accused Putin of ordering his assassination. He stated: "You may succeed in silencing me but that silence comes at a price. You have shown yourself to be as barbaric and ruthless as your most hostile critics have claimed." The deathbed statement, while not evidence in a formal legal sense, became one of the most widely publicised allegations of state-directed assassination in post-Soviet history.
Verdict
Confirmed. The UK Owen Inquiry (2016) found on the balance of probabilities that Lugovoy and Kovtun administered the Po-210, that the operation was an FSB operation, and that Putin probably personally approved it. The polonium trail, the weapon's state-only provenance, and the established motive — Litvinenko's public allegations about FSB corruption and organised crime ties — all support the confirmed finding. Russia's denial and refusal to cooperate are consistent with the inquiry's conclusions rather than with innocence.

SupportingStrongThe inquiry further found it was "probably" an FSB operation approved by then-FSB Director Patrushev and President Putin. The standard applied was the civil balance of probabilities, not criminal proof beyond reasonable doubt.
Polonium-210 contamination trail across London
SupportingStrongPo-210 traces were forensically identified at the Millennium Hotel Pine Bar, the Itsu sushi restaurant, and on Lugovoy and Kovtun themselves and on aircraft between London and Moscow, providing a forensic trail consistent with the operatives' documented movements.
Po-210 is only producible in state nuclear facilities
SupportingStrongPolonium-210 in the quantities required for weaponisation can only be produced in nuclear reactors. Its use as a poison is consistent with a state-level actor with access to nuclear facilities and inconsistent with a private or criminal operation.
Lugovoy elected to Russian parliament post-incident
SupportingRather than face extradition, Lugovoy was elected to the Russian State Duma in 2007, granting him parliamentary immunity. This is consistent with state protection of an operative and inconsistent with the behaviour of a private individual falsely accused.
Russia denied all involvement and refused extradition
DebunkingWeakRussia categorically denied involvement and refused UK extradition requests for both Lugovoy and Kovtun. Moscow described the Owen Inquiry as politically motivated. The denial is consistent with standard state deniability rather than with innocence.
Rebuttal
Denial without evidence of an alternative explanation, combined with refusal to extradite suspects and subsequent election of the primary suspect to parliament, is inconsistent with a credible innocence claim. The denial does not constitute evidence against the inquiry's findings.
Litvinenko's deathbed statement accused Putin directly
SupportingIn a statement dictated from his hospital deathbed, Litvinenko directly accused Vladimir Putin of ordering his assassination. While not formal legal evidence, the statement reflects Litvinenko's own assessment of who held responsibility for the operation.
Owen Inquiry applied civil, not criminal, standard of proof
DebunkingWeakThe inquiry's "probably approved" finding was made on the balance of probabilities, not beyond reasonable doubt. Some critics note this lower standard means the finding falls short of criminal guilt.
Rebuttal
The inquiry was explicit about the standard applied and did not claim criminal findings. The convergence of the forensic, intelligence, and circumstantial evidence supporting the civil-standard conclusion is substantial and has not been credibly challenged at either the civil or criminal standard.
Owen Inquiry 'Probably Approved' Finding Is an Inferential Standard, Not Direct Evidence
NeutralSir Robert Owen's 2016 Public Inquiry concluded that Vladimir Putin 'probably approved' the operation along with FSB Director Patrushev — an inference drawn from the pattern of evidence, Lugovoy's and Kovtun's documented movements, and institutional analysis of FSB operational culture. 'Probably approved' is the inquiry's inferential standard, falling short of the direct documentary or testimonial evidence that would establish approval in a criminal proceeding. Russia's denial, while self-interested, has not been countered by disclosed intercepted orders or direct witness testimony establishing the chain of command.
Polonium-210 Trail and Independent Forensic Evidence Is Forensically Robust
DebunkingStrongThe polonium-210 contamination trail documented by the UK Health Protection Agency traced Lugovoy's and Kovtun's movements across London venues — Berezovsky's office, the Millennium Hotel, British Airways aircraft — with a specificity that is extremely difficult to fabricate or misattribute. Po-210's reactor-production signature pointed to a state-controlled nuclear facility. The forensic chain is independent of Owen Inquiry inferences and establishes Russian state material involvement regardless of the specific chain-of-command question, making Russia's blanket denial of any state involvement implausible on the physical evidence alone.

Verdict
UK Owen Inquiry (2016): Andrey Lugovoy and Dmitry Kovtun administered polonium-210 to Litvinenko at the Millennium Hotel Pine Bar on 1 November 2006. The operation was an FSB operation probably approved by Putin. Po-210 traces confirmed at multiple London locations. Russia denied involvement, refused extradition, and elected Lugovoy to parliament.
Frequently Asked Questions
Did the UK inquiry conclude Putin ordered Litvinenko's murder?
The Owen Inquiry (2016) found on the balance of probabilities that the operation to kill Litvinenko was an FSB operation "probably" approved by Putin and then-FSB Director Patrushev. This is a civil-standard finding, not a criminal conviction, but it is the most authoritative official assessment of the killing and has not been credibly challenged.
Why was polonium-210 used instead of a conventional weapon?
Po-210 is nearly undetectable by standard radiation monitors, kills slowly, and in 2006 was not widely known as a potential assassination weapon. Its use was intended to produce a death that might be attributed to illness rather than poisoning. The inadvertent contamination trail it left across London proved to be its investigative undoing.
Has anyone been prosecuted for the Litvinenko killing?
No criminal prosecution has resulted in convictions. Lugovoy and Kovtun remain in Russia; Russia has refused all extradition requests. Lugovoy's election to the Duma in 2007 granted him parliamentary immunity. The UK Crown Prosecution Service has indicated it would prosecute if the suspects were ever extradited.
What did Litvinenko allege before his poisoning?
Litvinenko had authored books and given media interviews alleging FSB involvement in organised crime, the 1999 Russian apartment bombings that killed nearly 300 people, and the assassination of journalist Anna Politkovskaya (2006). His allegations were widely regarded in Russia as treasonous and by his supporters as the motive for his assassination.
