19/12/2003 (Agence Europe) - Professor Werner Weidenfeld, from the German Bertelsmann Federation, stated in a press release that, ""since the weekend o Core Europe has become a real structural option". According to Weidenfeld, it will be impossible to reach an agreement on the voting system at the Council unless Europe manages to develop lie a permanent integration model" and that countries like Spain and Poland take part in both economic integration and political union. However, experts from the foundation stress that the EU first needs to overcome the divergences and provide a constitution during the Irish presidency. According to Weidenfeld, in order to undo the points on which there was already agreement, the six founding counties and other countries will have to take a common initiative.
