US investment bank Oppenheimer & Co plans to double the number of dealmakers it employs in the City of London as it looks to grow its European mergers and acquisitions business.

Oppenheimer started to hire advisory bankers in the UK capital in 2014 and currently employs around 15. But Max Lami, a former Goldman Sachs banker who has been its chief executive for Europe, the Middle East and Africa since 2009, said in an interview that this figure could rise to 30 by the end 2018.
