Berezovsky post-mortem taking place on Monday

A post-mortem on the body of Russian oligarch and Kremlin critic Boris Berezovsky was to be carried out on Monday, British police said.

Police say there is no indication that anyone else was involved in his death of the 67-year-old, whose body was found at his mansion in Ascot, west of London on Saturday.

A pathologist from the Home Office interior ministry will undertake the examination instead of a local expert, due to the sensitivity of the case, police said.

“I would like to reiterate that we have no evidence of any third-party involvement at this stage and we will not speculate on the cause of death until the post-mortem examination has been carried out,” said Detective Chief Inspector Kevin Brown of the local Thames Valley Police force.

A spokeswoman said the results were expected by the end of the day, but it was not clear if they would be released to the public on Monday.

Berezovsky, who had survived at least one attempt to kill him in the past, was found dead on the floor of the bathroom at his luxurious home in Ascot, an upmarket town in Berkshire.

A member of his staff, believed to be a bodyguard, broke down the bathroom door after he had not heard from the tycoon for several hours.

Police said Berezovsky’s family had asked that some details of his death were not released until after the post-mortem in order to give them time to speak to his children first.

Friends have said Berezovsky had been depressed in recent months after losing a multi-million-pound court battle with Roman Abramovich, another British-based Russian oligarch who owns English Premier League football club Chelsea, the reigning European champions.

Forbes magazine published an interview on its website that Berezovsky gave to journalist Ilya Zhegulev on Friday in which he said his “life no longer makes sense” and that all he wanted to do was return to Russia.

But given that his friend and fellow Kremlin critic Alexander Litvinenko was killed by radioactive poisoning in London in 2006 — in what Litvinenko’s widow maintains was an assassination — police will continue to investigate.
