The next stage on the Juncker wagon is the apportionment of spoils ("Commissioners") amongst the 27 countries. The new President could jump either way: keep Britain onside and build a bridge or gift Cameron's appointee with some trivial portfolio last held by Malta or Estonia, showing that if you oppose, you will be punished.

Don't rock the boat! It may capsize!
