Man Group, the largest hedge fund manager in Europe, is understood to have cut two of its most senior sales staff as part of a shakeout in the business involving a "handful" of redundancies in the sales team following its acquisition of London-based rival GLG Partners last week.

Martin Keller, head of institutional sales and John Bennett, head of UK distribution have left the firm, according to a person familiar with the situation. The pair are two of a "handful" of sales departures across both firms, the person said. Keller and Bennett did not immediately respond to calls or emails. Man Group declined to comment.
