It’s a grim winter’s day in Berlin, and the political climate matches the weather. Everywhere Angela Merkel looks there are storm clouds, as the values she has upheld all her career come under sustained attack. At the start of a new decade, Europe’s premier stateswoman suddenly seems to be on the wrong side of history.

Shortly, the UK will leave the EU. A volatile US president is snubbing allies and going it alone in the Middle East. Vladimir Putin is changing the Russian constitution and meddling in Libya and sub-Saharan Africa. Trade tensions continue, threatening the open borders and globalised value chains that are the cornerstones of Germany’s prosperity.

Ms Merkel, a former physicist renowned for her imperturbable, rational manner is a politician programmed for compromise. But today she faces an uncompromising world where liberal principles have been shoved aside by the law of the jungle.
