An oligarch who has supplied building materials to the Russian military machine and for construction in occupied areas of Ukraine is being assisted by Morgan Stanley and Allen & Overy in his attempt to gain control of a huge Russian oil asset, the Guardian can reveal.
Sergey Kolesnikov, originally from Russia but now a Maltese citizen under its “golden passport” scheme is estimated to be worth $1.2bn (£940m) as a result of the building materials business he co-founded.
