A former Goldman Sachs dealmaker, who claims to have worked on some big Russian transactions at the US bank, has written an open letter to chief executive David Solomon asking he stay on the “right side of history” by shutting down bank operations in Russia. 

Georgy Egorov, who left the bank in 2010 and went on to lead UBS’s emerging markets equity capital markets division, worked on Russian deals at Goldman Sachs while based in London. A Goldman Sachs spokesman declined to comment.
