A long-running and revealing legal dispute between one of Britain's oldest and most publicity shy buyout firms, Charterhouse Capital Partners, and a former director has drawn to a close.

Geoffrey Arbuthnott, the former partner of Charterhouse Capital Partners who brought legal action against the British private equity firm last year, has had his appeal against the firm dismissed. Arbuthnott argued in a six-week case last year that he was forced to sell his shares in Charterhouse for less than their true value. He lost the case in May 2014, but appealed the decision in court last month.
