The Ontario Teachers' Pension Plan, one of the most aggressive at making buyout investments, has promoted a key player in the record $48.5bn (€35.6bn) buyout of Canadian phone company BCE to chief executive.

Jim Leech, senior vice president of the C$106bn (€71bn) fund, takes over with effect from December 1. The fund was among a group that agreed to buy BCE in a Canadian record in July.
