A former director of Russian state airline Aeroflot found dead in a London apartment on Monday was a close affiliate of the late oligarch Boris Berezovsky, according to local media reports, APA reports quoting AA.
A police officer stands at a cordon around the bench where former Russian intelligence agent Sergei Skripal and his daughter Yulia were found after they were poisoned, in Salisbury, Britain March 11, 2018.
Glushkov had worked for Russian airline Aeroflot and at Berezovksy's LogoVAZ auto company.
In 2000, he was arrested in connection with the embezzlement of Aeroflot's funds, and later charged with fraud and money laundering. He spent five years in jail and was freed in 2004.
In 2010, he fled to the United Kingdom, where he was granted political asylum.
Billionaire and business oligarch Berezovsky later ran afoul of the Kremlin when he publicly denounced Putin and brought a lawsuit against his ally, fellow billionaire Roman Abramovich.
Glushkov told the London court he had effectively been taken hostage by Putin's administration, which wanted to pressure Berezovsky to sell his stake in the TV station ORT.
Berezovsky is one of 14 Russians whom USA intelligence services believe were assassinated in the United Kingdom, according to an investigation by BuzzFeed News. In 2017, a Moscow court reviewed his case and he was sentenced to eight years in prison in absentia for stealing as much as $123 million from Aeroflot in the 1990s.
Berezovsky was found hanged in his Berkshire home in 2013 in an apparent suicide.
Mr Glushkov's next-door neighbour, who did not want to be named, said he was a "nice man", who used to give his neighbour's children gifts at Christmas.
Russian media said he was granted political asylum in Britain in 2010. Those found responsible for this use must be held accountable for their actions, " he said.
Russian Federation has dismissed accusations of any involvement in the Skripal case as "nonsense", saying it would only cooperate with the British investigation if it receives samples of the nerve agent believed to have been used.
The Russian Foreign Ministry, meanwhile, says it has handed the British ambassador a note of protest regarding the accusations, calling them "baseless", "provocative" and "another unscrupulous attempt of the British authorities to discredit Russia".
