78 - Was journalist Ahmed Mansour arrested by mistake? Plus: the Queen visits Berlin and a giant sculpture which doubles as a slide!

While we first reported the story of the Al-Jazeera journalist's arrest last week, the past few days saw an interesting twist to the tale of Ahmed Mansour. Why was he arrested in the first place? And were murky forces behind his release? Berlin-based journalist Ben Knight joins us to explain.

In this episode, we take a look at the visit of UK's Queen Elizabeth. Why is the German media so obsessed with British royalty? 

We'll also be taking you to a giant metal art installation... which doubles as a slide. And is part of a furniture museum. And a factory. Confused? All will be revealed. 

As always, we'll also have the rest of this week's news in brief.
