Interesting angle. Fits with what little I know of Boris Abramovich Berezovskiy.
There was a popular tele-journalist in Moscow back in the late 1990s who ran afoul of mafiosi and had to pay some protection money. Supposedly he had to give the money to Berezovskiy, who was to hand it off to the gangster. Berezovskiy instead went shopping, and the journalist ended up dead.
BAB is also the Russian businessman who invented the salary-less payroll, where employees wouldn't get paid, but had to keep getting salary advances to survive month to month. If they quit, "they'd never work in Moscow again", in addition to losing their back pay. The idea got so popular among Russian businessmen in the mid-1990s that pretty much nobody was getting paid.
BAB paid off Yeltsin through frequent luxury gifts and vacations. He even hired Yeltsin's son-in-law (the husband of Tanya Dyachenko, who pretty much ran the Kremlin during Yeltsin's frequent drunks) to be on the board of the airline Berezovskiy owned at the time, Aeroflot.
His role (along with General Lebed) in ending the first Chechen war was probably the reason he can't safely venture outside. Before he fled, several tapes of BAB talking on the phone with terrorists were aired. I had a lot of transcripts posted here, but when FR went to its new format, lots of history disappeared as well.
I'm amazed that UK decided to give BAB and assorted Chechen terrorists asylum, but the world long ago moved beyond my comprehension.
