Yeah, that's pretty indicative of the standard of the EU 'leadership'.
What a childish prat.
Mr Juncker went on to say he was banning any informal and secretive negotiations on Britain's departure from the EU.
He said there will be no secret meetings between UK, national governments and commissioners in the corridors. "I ban that."
Well, that sure as Hell ain't childish. That's mature decisive leadership, that is.
