Macron suggested EU integration should continue at two or three speeds. He cited the 19-nation euro area and the 26-state borderless Schengen zone as examples.
"I am in favour of changing the treaties. We’ve reached the point when this needs to be done and we should not be afraid. The rule is simple: naysayers should not stop the others," he stressed.
