http://en.wikipedia.org/wiki/Russian_oligarchsA significant number of Russian oligarchs have bought homes in upscale sections of London, United Kingdom, which has been dubbed "Moscow on Thames". Some, like Boris Berezovsky, Konstantin Kagalovsky and Abram Reznikov, are expatriates, having left Russia permanently. Most own homes in both countries as well as property and have acquired controlling interests in major European companies. They commute on a regular basis between EU and Russia; in many cases their families reside in London, with their children attending school there. In 2007, Abram Reznikov bought one of Spain's mega recycling companies, Alamak Espana Trade SL, while Roman Abramovich, considered the wealthiest of the oligarchs, bought the English football club, Chelsea F.C., in 2003, and has spent record amounts on players' salaries.
So, a large number of Russian oligarchs live in London, some having settled there permanently and others coming to and from from Russia. Do none of these people have UK bank accounts? Is all of the money that they have there clean? Of course they do, and of course it isn't. So how come it is OK for the UK to handle these people's dubious money?
Incidentally, although the monopolistic Axel Springer media group has portrayed the Cypriot economy as being little more than a system for laundering Russian oligarch's money, I know of no Russian oligarch that lives in Cyprus. Perhaps somebody would correct me if I am wrong.
