“Succession will continue to be led by its experienced management team, headed by chairman Ray Pierce.”
Mr Chamberlain began his career at Merchant Investors before moving to Royal Life and St James’s Place.
In 1999 he became national development director of Zurich Financial Services before leaving in 2003 to found Thinc Group.
When this was sold to Axa in 2007 and became Bluefin Mr Chamberlain launched a consultancy firm called Ultimate Succession, which eventually evolved into his consolidation business.
