Alexander Litvinenko
Alexander Valterovich Litvinenko( 30 August 1962 or 4 December 1962 by father's account – 23 November 2006) was a British naturalised Russian defector and former officer of the Russian FSB secret service who specialised in tackling organized crime.
According to US diplomats, Litvinenko coined the phrase Mafia state.
In November 1998, Litvinenko and several other FSB officers publicly accused their superiors of ordering the assassination of the Russian tycoon and oligarch Boris Berezovsky.
Litvinenko was arrested the following March on charges of exceeding the authority of his position.
He was acquitted in November 1999 but re-arrested before the charges were again dismissed in 2000.
He fled with his family to London and was granted asylum in the United Kingdom, where he worked as a journalist, writer and consultant for the British intelligence services.
During his time in Boston, Lincoln, Litvinenko wrote two books, and" Lubyanka Criminal Group", wherein he accused the Russian secret services of staging the Russian apartment bombings and other terrorism acts in an effort to bring Vladimir Putin to power.
He also accused Putin of ordering the murder in October 2006 of the Russian journalist Anna Politkovskaya.
On 1 November 2006, Litvinenko suddenly fell ill and was hospitalised in what was established as a case of poisoning by radioactive polonium- 210; he died from the poisoning on 23 November.
He became the first known victim of lethal polonium 210- induced acute radiation syndrome.
The events leading up to this are a matter of controversy, spawning numerous theories relating to his poisoning and death.
A British murder investigation pointed to Andrey Lugovoy, a former member of Russia's Federal Protective Service, as the prime suspect.
The United Kingdom demanded that Lugovoy be extradited, which is against the Constitution of Russia, which prohibits extradition of Russian citizens.
Russia denied the extradition, which led to the straining of relations between Russia and the United Kingdom.
After Litvinenko's death, Marina Litvinenko, aided by biologist Alexander Goldfarb, pursued a vigorous campaign through the Litvinenko Justice Foundation.
In October 2011, she won the right for an inquest into her husband's death to be conducted by a coroner in London; the inquest was repeatedly set back by issues relating to examinable evidence.
A public inquiry began on 27 January 2015, and concluded in January 2016 that Litvinenko's murder was an FSB operation that was probably personally approved by Vladimir Putin and Nikolai Patrushev who was at the time Director of FSB.

Igor the Assassin is an SVR and former KGB officer who allegedly killed Alexander Litvinenko and escaped back to Russia.

His name and true identity remain unknown.
He was said to be a former Spetznaz officer born in 1960 who is a judo master and walks with a slight limp.
