Jeffrey has joined from MGPA an independent private equity real estate investment advisory business and is expected to join M&G in London from July 2012.
His most recent role at MGPA, where he has worked for more than 13 years, is Global Chief Investment Officer based in Singapore.
Martin Moore, managing director of Prupim for the past 15 years will become chairman of the real estate fund management business to enable a smooth handover to Jeffrey before he retires post-2012.
Michael McLintock, chief executive of M&G, said: "With an impressive record of leadership roles in the international real estate investment sector, Alex is extremely well-qualified to lead the next phase of Prupim’s growth."
Prupim has around £15bn invested in properties across Europe, North America and the Asia Pacific region.
