What awaits the new EU leadership?

The EU’s new troika of leaders has emerged after months of intense negotiations between member states.

Donald Tusk, the prime minister of Poland, has been elected to succeed Herman van Rompuy as president of the European Council. Jean-Claude Juncker, Luxembourg’s former prime minister, has been designated as the European Commission’s next president. And Federica Mogherini, Italy’s recently appointed foreign minister, has been chosen to become the next high representative for foreign affairs and security policy.
