Brian and Maggie is a Channel 4 dramatization of the interview that led to the downfall of Britain’s former prime minister. Succession and Killing Eve star Harriet Walter is taking on the role of controversial ex-prime minister Margaret Thatcher.
The show, formerly called Brian and Margaret, dramatizes the story of her last ever TV interview, which some believe was the final nail in her prime ministerial coffin. The 45-minute interview was carried out by her old friend and fearsome political inquisitor, the former Labour MP Brian Walden (played by Steve Coogan), who struck numerous blows that were seen to damage her reputation as a leader beyond repair. Thatcher resigned the following year and the pair never spoke again after what is regarded as one of the most infamous political exchanges of all time.
