US private equity company General Atlantic is in discussions to acquire a third of UK-based Hyperion.

Hyperion owns broker Howden and underwriter Dual.

British private equity group BP Marsh, which owns 13.8% of the company, confirmed recently it is in discussions to sell its stake, while venture capitalist 3i is also reported to be in talks with General Atlantic to sell its 19.1% stake.

General Atlantic was a founding investor in insurance technology provider Xchanging.
