USM is named after it's main shareholders, Alisher Usmanov, Vladimir Skoch and Farhad Moshiri ... Usmanov, Skoch, Moshiri ... U , S , M ... USM
It says it right here -
http://usm-group.com/company ... how about you bother to do some research?
And OF COURSE there will be links between Blue Heaven Holdings - Bridgewaters - USM because they've used Bridgewaters before so why would they not use them again?! As far as I can see there is nothing in the PL rules which state that you can't use an accountancy firm or business services of a company you've already delt with or have ties with e.g. an employee working for both.
Any way... Usmanov IN!
