"To conclude, the Group of the Party of European Socialists would like to state that it wholeheartedly agrees with the content of this report although it regrets, as does the rapporteur himself, Mr Varela Suanzes-Carpegna, that there is a lack of proposed measures from the Commission on combating the main enemy of our fleet and of the conservation of fishery resources today. This enemy is none other than those vessels flying flags of convenience."
En guise de conclusion, le groupe socialiste manifeste son plein accord sur le contenu de ce rapport en regrettant - à l' instar du rapporteur M. Varela lui-même - l' insuffisance des mesures proposées par la Commission pour la lutte contre ce qui constitue aujourd' hui le principal ennemi de notre flotte et de la préservation des ressources halieutiques : les navires battant pavillon de complaisance.
