Eighteen months on from using no fewer than eight advisers on its deal for a 70% stake in International Power, GDF Suez has whittled that list down to just two for its bid for the remaining stake, with independent advisers Rothschild and Ondra Partners winning out.

GDF Suez yesterday announced it had bid £6bn, or $9.5bn, for the remaining 30% stake in International Power that it does already own.
