Exiled critic of Vladimir Putin Nikolai Glushkov was murdered and then strung up to make it look like he committed suicide, senior sources claim. The 68-year-old was found dead by his daughter, Natalia, at his suburban home in New Malden, south London on Monday night - just eight days after the nerve agent attack on spy Sergei Skripal. Mr Glushkov was one of the last surviving members of an ill-fated circle of Russian exiles - led by Putin's enemy Boris Berezovsky - who was also found dead five years ago.
