Litvinenko poisoning: the main players:
Alex Goldfarb and Alexander Litvinenko met in a Russian prison. In the late 1990s, Mr Goldfarb was director of a George Soros-funded project to tackle TB in the Russian penal system.
Since arriving in the UK six years ago, Mr Litvinenko had been close to the man who was once one of the wealthiest entrepreneurs in Russia, Boris Berezovsky. Mr Berezovsky, 60, is thought to own the north London house where Mr Litvinenko lived, and is said to have employed him as an adviser in the past.
Another figure whose hand could be detected as the strange poisoning story unfolded was Lord Bell of Belgravia, the man who, as Tim Bell, came to be synonymous with the advertising campaigns that helped usher the Tories to power in 1979.

Former spy 'poisoned by Russians' dies

The former Russian spy who claimed he was poisoned by his country's secret service died last night.
Alexander Litvinenko died following a rapid deterioration of his condition
Alexander Litvinenko, 43, died in intensive care at 9.21pm. University College Hospital, which had been treating the former Federal Security Service colonel since Friday, said the medical team had done everything they could to save him.
However, the hospital admitted that despite extensive tests, it still could not confirm the cause of death.
Scotland Yard's counter-terrorism unit, which is investigating the case, said that it was treating his death as "unexplained". It was not currently a murder inquiry.
Shortly before his death Mr Litvinenko is reported to have told a friend: "The bastards got me. But they won't get everybody."
Both the Kremlin and Russia's security agencies have denied any involvement in his alleged poisoning.
It was unclear last night whether there would be any diplomatic ramifications following Mr Litvinenko's death.
It came after he was placed on a ventilator following a cardiac arrest. He had been receiving treatment under police guard.
Mr Litvineko's condition deteriorated sharply overnight on Wednesday. He experienced the failure of his digestive system, liver and bone marrow, which affected his blood, and also had problems with his speech.
Confirming news of his death, a spokesman for University College Hospital said last night: "He was seriously ill when he was admitted to UCH on Friday November 17, and the medical team at the hospital did everything possible to save his life.
"Every avenue was explored to establish the cause of his condition and the matter is now an ongoing investigation by detectives from New Scotland Yard."
Mr Litvinenko's wife, Marina, had been at his bedside all week. She has still to speak publicly.
Her husband, a fierce critic of President Vladimir Putin's Russian regime, was allegedly poisoned on Nov 1.
It is known that he had two meetings that day — one at a hotel and another at a sushi restaurant in central London. He later fell ill and was taken to Barnet General Hospital where he was treated until his condition worsened last Friday, when he was transferred to University College Hospital.
Scotland Yard said last night: "Inquiries continue into the circumstances surrounding how Mr Litvinenko became unwell.
"The matter is being investigated as an unexplained death."
