BRUSSELS, Sept. 21 (UPI) -- The idea of establishing a group of "core" European Union countries has been raised by Italian Prime Minister Silvio Berlusconi, observers say.
Berlusconi made the comments last week to Italian media when he was asked what the future of the Lisbon Treaty would be should Irish voters reject it a second time, the EUobserver reported Monday. The publication quoted Berlusconi as telling Italian state broadcaster RAI News 24, "We need to completely revisit the current functioning of Europe to create a core of states that operate beyond unanimity."
