The chief executive of the London-based brokerage acquired by Cowen Group as part of its purchase of New York-headquartered Convergex Group has left just months after the deal completed.

Philip Gough, who had been CEO of Convergex's London-based brokerage since January 2015, left the group towards the end of 2017, according to Companies House filings, ending another chapter in his more than 30 years in capital markets.
