You might not think of the corridors of Brussels as a particularly spiritual place, but all kinds of religious groups are jostling for influence there. This week we delve into the world of religious lobbying with the French journalist Quentin Ariès. Also this week: a secret passage, winds of change in Slovakia, and the power of the Paris agreement.

This week, the kid from Hamburg who grew up to become one of the most powerful forces in global fashion. Karl Lagerfeld built not one but three hugely successful brands. After his death last week at the age of 85, we're exploring the flaws, quirks and legacy of this complicated man with the help of Fiachra Gibbons, culture editor at Agence France-Presse and long-time observer of 'the Kaiser'. We also discuss Europe's rising problem with anti-Semitism, some good news for Serbia's gay first couple, and how to make it big in Finland.

Our guest this week is Akbar Ahmed, one of the world's leading experts on Islam, who has just published a major new study on Europe's Muslims. We enjoyed our conversation so much that we'll be releasing it in full as a bonus episode, so look out for that later in the week.

We couldn't have two more different interviews for you this week: we're talking anti-Semitism in Germany and the art of remaining zen on a beach in Scotland.

After two German rappers sparked national outrage with lyrics about the Holocaust, Human Rights Watch Germany's chief Wenzel Michalski is on the line to talk about his all too personal experience of Europe's rising anti-Semitism problem.

Why throw stones when you can turn them into art instead? Scottish photographer Andy Buchanan brings us the weird, wonderful and unexpectedly hilarious story of the European Stone Stacking Championships.

Plus, Macron Does America and Bulgaria Does It Wrong. And why not stick around and Take A Chance On Dominic's happy ending this week?
