Why Russians flee to the UK

Not every Russian who makes it to the UK is safe, but it appears that they are safer than they would be if they stayed in Russia.  May who were close to Putin, or the Russian state and have become British citizens have good reason to stay away from Russia, and the accidents that have happened to many Russians in Russia (and some outside it) appear to be the reason.

Leonid Shulman is one, though he had issues with chronic pain and also was under investigation when he died. The next is Alexander Tyulakov who hung himself. Mikhail Watford died despite being in the UK. Vasily Melnikov died with his wife and two children and the deaths of family also occurred with Vladislav Avayev who was found dead with his wife and thirteen year old daughter. Sergey Protosenya died outside Russia, this happening in Spain with his wife and daughter. Andrey Krukovsky died alone when hiking in a fall off a cliff. Alexander Subbotin died after getting a cure from a shaman. Yuri Voronov died in a suicide at his swimming pool. Dan Rapoport fell out of his window at his home in the USA while Ravil Maganov also fell out of a window, this being in hospital however the camera's at the time being turned off so that they could be repaired. Ivan Pechorin fell of his boat and drowned. Vladimir Sungorkin had a stroke, and the latest, Anatoly Gerashchenko also had a fall. 

Normally, I would say that this is too much of a co-incidence to be just due to Putin, but considering his invasion of Ukraine and the incompetence shown in his invasion, I do think that Putin is behind this. The question is what will others who may be on the list to have accidents do about the ever increasing death list.
