SIR Martin Sorrell, the boss of advertising titan WPP, is poised to join the advisory board of British wealth management firm Stanhope Capital.
He will take up a role on the advisory board of the firm, which manages funds totalling $7.5bn (£4.6bn), alongside former BP chief Lord Browne.
Lord Browne was appointed to chair the advisory board last year.
Sir Martin also joins Stanhope chairman and managing partner Daniel Pinto, who he has known for about 15 years.
The advisory board has been set up by Stanhope in order to develop its investment strategy, which will be lent weight by the expertise and experience of Sir Martin.
More additions to the firm’s advisory board are expected over the coming months.
Stanhope recently acquired rival wealth management firm Jewson Associates, with Jewson being folded in to create a new division specialising in the charity sector.
Stanhope was set up in 2004 by investment banker Pinto and Julian Sevaux, another financier, formed around a group of prominent British and European families seeking to manage their wealth.
