Henry Keeling, chief executive of reinsurance broker Guy Carpenter’s international operations, will leave the company on 30 June.

It is not yet clear who will replace Keeling or what he plans to do next. Guy Carpenter declined to comment.

Keeling’s decision follows a management reshuffle at the top of Guy Carpenter. Former chief executive Peter Zaffino has become president and CEO of insurance broker Marsh, one of Guy Carpenter’s stablemates in the Marsh & McLennan group of companies.

Alex Moczarski, previously head of Marsh’s international divisions, has replaced Zaffino as Guy Carpenter’s new CEO.

Keeling joined Guy Carpenter in August 2009, having previously served as chief operating officer of Bermudan insurance group XL and chief executive of XL Re’s international operations.
