The EU must define how far it can expand with new member states

How large can the European Union be? Is there a limit to its enlargement? And if so, what is that limit? If the EU were to include 30 or more member states, will it still have unity? The European Parliament voted in 2006 for a resolution on future EU enlargements. Two MEPs give their views in this article: Elmar Brok (EPP-ED, DE), who chairs EP's foreign affairs committee and prepared the resolution, and Jan Marinus Wiersma (PES, NL), who is his group’s spokesman for foreign affairs and wrote a book on the borders of the EU.
