What can the UK learn from Germany? In Berlin, BBC disinformation and social media correspondent Marianna Spring meets a whistleblower who stopped writing for a conspiracy theory newspaper in his country because he feared it was becoming more radical. Marianna uncovers more about the connections between the German paper and a failed coup attempt, and unpicks what it can tell us about our own conspiracy theory movement in the UK.
