Mrs Merkel brought unity and peace to the EU’s high table, which was unusual as she seldom had much to say. Like many German politicians she was unimaginative about how to stop financial rot from spreading to countries like Italy. But she had an asset that most leaders can only dream of - authority. When she talked, others listened. The arguing stopped. If her present attempts to form a coalition government fail and she steps down, who will have the same effect? The Brexit vote was representative of a big political undercurrent in European politics, a force that was moderated by Merkel. Without her, or anyone else with a unifying idea about the EU, the cracks in its thin ice could become dangerous splits. Emmanuel Macron draws the support of other radicals like Jean-Claude Juncker, but their vision of Europe is at odds with the view of most. Other leaders are silent.
