08/04/2003 (Agence Europe) - Enlargement is a historical and ethical necessity that will require root and branch changes but detail has never been achieved, affirmed the Co-President of the Greens/EFA group, Daniel Cohn-Bendit in Strasbourg. He said people should be aware that enlargement would send Europe into a crisis and enlargement would be more expensive than the Commission says. Governments represent national egotism. The new Member States have to understand, he said, that they only have one true ally, the European Parliament.
