How long can the new French PM last? Is Brazil right to switch off X? How did AfD win in Germany?

It has been a week which saw France finally appoint a new prime minister. A mountain hiking, smooth-talking septuagenarian – Michel Barnier. Monsieur Brexit, former EU point man negotiating Britain’s divorce. He has served in the cabinet of many French Presidents in decades gone by. Now, he is back as the oldest PM in the French fifth Republic replacing the youngest one! But why Barnier? And why did he want the job? Is it because he is the master of eggshell diplomacy?
