The idea of a permanent president of the European Council was resisted by many smaller countries. But now it is being created, it would be ludicrous to fill it with a minor figure; a Juncker or a Schüssel. To the outside world – India or China, say – the president will speak for Europe. If the EU wants to be a serious global actor, that points to a world figure. Unless Ms Merkel steps forward, which is improbable, the only such person in the running is Mr Blair.
