David Collier joins Jonathan Sacerdoti for one of his clearest and most wide-ranging conversations yet about Britain, the media, extremism and the pressures reshaping public life. Drawing on years of undercover work inside activist movements, online networks and university groups, Collier explains what he has seen from the inside — and why he believes the country is struggling to understand the forces acting on it.

Collier didn’t set out to become an investigator. His career began in Israel, before returning to a Britain he barely recognised. That shock pushed him to look more closely: into anti-Israel activism, into how information flows from Gaza to British newsrooms, and into the way online platforms drive people toward extremes. The picture he’s built over years of research has made him one of the most cited independent analysts of media bias and modern extremism in the UK.

Watch if you want a clear, detailed account of the pressures shaping Britain — from someone who has spent years mapping them.
