THE LITVINENKO POISONING

THE CLAIM

That the Russian state murdered a former FSB officer and British citizen in London using a radioactive isotope, and that the operation was approved at the highest level.

THE THEORY, AS ITS PROPONENTS TELL IT

The evidence here is physical and unusually conclusive, because the weapon chosen was one that records its own movements.

Polonium-210 is an alpha emitter, undetectable by ordinary radiation monitoring and lethal in microgram quantities, which is presumably why it was selected. It is also produced in meaningful quantity almost exclusively in state nuclear reactors, and it contaminates everything it touches.

The contamination trail was mapped across London: hotel rooms, a restaurant, an office, bar stools, and the seats of specific aircraft on specific flights. Investigators could reconstruct the suspects' movements and identify a first, failed attempt weeks before the successful one.

The 2016 public inquiry, with access to secret intelligence in closed session, concluded that Andrey Lugovoy and Dmitry Kovtun poisoned Litvinenko, that they were acting on behalf of the FSB, and that the operation was probably approved by the FSB director and by President Putin. Russia refused extradition; Lugovoy was subsequently elected to the Duma.

WHAT IS KNOWN

The cause of death and the isotope are established beyond dispute by post-mortem and by the contamination survey.

The physical trail is documented in detail and matched the suspects' known movements, including aircraft seat contamination on flights they took.

The inquiry's findings on state responsibility relied partly on closed intelligence material that has not been published, which is the principal objection to it.

The European Court of Human Rights ruled in 2021 that Russia was responsible for the assassination.

EVIDENCE FOR

• A polonium-210 contamination trail reconstructing the operation across multiple sites and flights.
• An isotope obtainable in practice only from a state reactor programme.
• A UK public inquiry finding, and a subsequent European Court of Human Rights judgment.
• Russia's refusal to extradite, and the subsequent political elevation of one suspect.

EVIDENCE AGAINST (THE ATTRIBUTION AT THE TOP)

• The finding that Putin probably approved it rests substantially on closed intelligence material that has never been published or tested publicly.
• Russia has consistently denied involvement and offered alternative accounts, none of which account for the polonium.
• Probably approved is the inquiry's own careful phrasing, and it is frequently quoted as though it were a finding of certainty.

ASSESSMENT

Confirmed as a state assassination, with the attribution at the very top stated by the inquiry at the level of probability rather than certainty. This office keeps that distinction because the inquiry did. What is not in any doubt is the physical case: a reactor-produced isotope, a contamination trail that mapped the operation, two identified men, and a state that will not surrender them. Compare OSA-170, twenty-eight years earlier, where the technology was a modified umbrella and the attribution took the fall of a government to confirm.

WHAT WOULD CHANGE THE GRADE

• CONFIRMED as a state assassination on physical evidence: polonium-210 is produced in quantity only in state reactors, and its contamination trail reconstructed the operation across hotels, an office and specific aircraft seats, including a failed first attempt weeks earlier.
• Stated at the level of probability, not certainty, and frequently misquoted: the 2016 inquiry found the operation was probably approved by the FSB director and by President Putin, relying partly on closed intelligence that has never been published.
• The European Court of Human Rights ruled in 2021 that Russia was responsible. Both named suspects remain in Russia, and one was elected to the Duma.
