When journalists burn their sources

What can journalism learn from Fire and Fury, Michael Wolff's blockbuster account of life inside President Trump's White House? How does a reporter persuade the rich and powerful to let them into their world - and when they've got what they wanted, is it ever OK to burn their sources on the way out? Also, why the tech giants are now taking the digital detox trend very seriously.

Andrea Catherwood is joined by Polly Curtis, HuffPost UK editor in chief, Maija Palmer, social media journalist at The Financial Times, Camilla Long of The Sunday Times, Patrick Forbes, documentary maker, and lawyer and writer Arwa Mahdawi.
