How briefings work and when they mislead markets

With the President squaring up to the BBC, veteran Radio 4 broadcaster John Humphrys gives us his views about the crisis at the corporation. Also on the programme, we hear about tourists chasing pigs in the New Forest during pannage season. We have a briefing on briefing from Patrick Maguire, Chief Political Commentator at The Times. And the papers are reviewed by Ulrika Jonsson, Calum Leslie from Radio 1 and Anna Gross of the Financial Times.
