The 60th anniversary of the Rome Treaties, treaties establishing the European Union, is tomorrow Saturday, March 25 and several EU heads of state or government will meet in Rome to reflect on the state of the bloc and the future of the integration process.

However, the famous mantra of an "ever closer union" has come under fire with rising populist movements throughout the continent and Brexit.

Now, other member nations have suggested the concept of a more distant relationship.

Increasingly it appears that the future will have less consensus and more decisions where groups of member nations advance on their own when faced with resistance, Luxembourg Prime Minister Xavier Bettel said in an interview with the Associated Press.

"I'd rather have a two-speed Europe than a dead-end and no speed," Bettel said.
