Barclays on Monday confirmed that its global head of mergers, Paul G. Parker, is leaving, becoming the latest high-profile departure from the British bank.
The move was announced in a short internal notice. A spokesman for the bank declined to comment.
Mr. Parker is the latest in a string of senior executives who will be leaving Barclays, as it prepares to shrink the size and costs of its investment bank. Last week, three other bankers â" Hugh McGee III, the head of the firmâs Americas unit; Ros Stephenson, the global chairman of its investment bank; and Robert Morrice, the head of its Asia Pacific arm â" also disclosed their impending departures.
Barclays has been moving to scale back its investment banking, reflecting tougher new regulations and fallout from a rates-fixing scandal that led to the departure of Robert E. Diamond as chief executive. The bank is expected to reveal its outlines for its newly reorganized investment bank this week.
Word of Mr. Parkerâs impending departure began to spread on Friday, after Ms. Stephenson and Mr. Morrice announced their own exit plans.
A longtime deal maker, Mr. Parker had kept busy even until late last week. Among the assignments on his plate are Valeantâs $45.6 billion takeover bid for the maker of Botox and Comcastâs $45 billion deal for Time Warner Cable.
He joined Barclays in 2008, when the firm took over the American banking operations of Lehman Brothers, where he served as co-head of mergers and acquisitions â" and helped arrange the transaction.
