Alistair Coleman - Disinformation, Dictators and Propaganda

Join BBC journalist Alistair Coleman as he guides us through the world of fake news and its consequences, and how the corporation separates fact from fiction. And hear about countries where the news is so tightly controlled at the whim of ruling dictators that citizens only ever hear one voice, be they North Korea's Kim, Turkmenistan's Berdimuhamedovs or - of course- Russia's Putin.
