MOSCOW, April 4 (Reuters) – Investors from Britain bought almost 50 percent of Polyus shares sold by the gold producer’s controlling shareholder, according to deal bookrunner VTB Capital. Polyus said on Thursday that its controlling shareholder, Polyus Gold International Ltd (PGIL), had sold a 3.84 percent stake in the company via an accelerated bookbuilding (ABB). Russian investors bought about a third of the other half, while the remaining shares were acquired by investors from Europe, the United States and Asia, said Boris Kvasov, co-head of equity capital markets at VTB Capital.
