PARIS, Sept 24 (Reuters) - The head of French warplane

maker Dassault Aviation said on Wednesday he was ready

to co-operate on fighter developments with anyone designated by

the French governnment.

Speaking to French deputies a day after saying Dassault was

capable of developing a fighter alone, CEO Eric Trappier set out

differences with Germany over a new European fighter but left

the door open to agreement on the next phase: "We can co-operate

tomorrow, but we have to do it effectively," he said.
