"Ladies and gentlemen, finally, I would like once again to congratulate the Ombudsman, Mr Söderman, on the work which he is doing, on the significant increase in his actions and his work, on his cooperation, although he sometimes makes criticisms, but that is his job and his role, and we in the Commission understand that."
Mesdames et Messieurs, pour terminer je voudrais féliciter à nouveau le médiateur, M. Söderman, de son travail, de plus en plus important, de ses actions, de plus en plus nombreuses et de sa collaboration, parfois critique, mais, comme l'assume la Commission, telle est sa tâche et sa fonction.
