What if one forgotten law changed the course of history — and we ignored its lesson? In this explosive interview, Matthew Syed – bestselling author, Times columnist, BBC broadcaster and former Olympian – joins Andrew Gold on Heretics to uncover the shocking truth about cousin marriage, tribalism, immigration, and the hidden ban that built Britain. From the 6th-century ban on cousin marriage that forced people to look beyond their tribe, to today’s siloed communities in places like Rochdale and Bradford, Syed argues that ignoring these lessons has left Britain vulnerable. We dive into immigration policy, Labour’s failures, the rise of cultural relativism, and why banning cousin marriage may be the only answer left.
