Four senior bankers at Credit Suisse, including former head of investment banking Bayo Ogunlesi, have set up the bank's first infrastructure fund, a joint venture with US conglomerate General Electric.

Ogunlesi, who was head of investment banking for two years before being moved aside by chief executive Brady Dougan in August 2004, will be chairman and managing partner of Global Infrastructure Partners, the $1bn (€778m) joint venture with GE Infrastructure.
