Invesco, part of the Anglo-American Amvescap investment group, has been hit by several high-level resignations, including that of Parag Saxena, managing partner and head of the private equity practice in New York, who announced his decision last week.

Alessandro Piol, a general partner responsible for IT investments, and Howard Goldstein, a general partner on the direct investment team, resigned at the same time. Piol will work until the end of next month. Goldstein has left.
