The president of the European Commission has fanned the flames of British debate over EU membership by insisting that fiscal union in the eurozone will lead to “intensified political union” for all 27 member states.
“This is about the economic and monetary union but for the EU as a whole,” he said.
“The commission will, therefore, set out its views and explicit ideas for treaty change in order for them to be debated before the European elections.”
“We want to put all the elements on the table, in a clear and consistent way, even if some of them may sound like political science fiction today. They will be reality in a few years’ time.”
