Patrick Degorce, a former leading light at The Children’s Investment Fund, has launched his new hedge fund, called Theleme Partners, with an estimated $200m (£122m) under management.

Mr Degorce – until January this year one of TCI’s founding members – made his name alongside chief executive Chris Hohn as one of the architects of the London-based fund’s high-profile attacks on some of the world’s largest companies.
