Brian and Maggie true story: Inside the real-life fallout between Margaret Thatcher and Brian Walden Brian and Maggie is a recreation of Margaret Thatcher's final TV interview with broadcaster Brian Walden (played by Steve Coogan), which shattered their relationship.
It took a number of attempts for him to win a seat as a Labour MP for Birmingham Ladywood, but became disillusioned with the party and had even considered defecting after Thatcher was elected Conservative leader in 1975.
Instead of defecting, he resigned in 1997 and turned his attention to broadcasting, landing his own show called The Walden Interview.
He forms an unlikely bond with his first guest, Conservative leader Margaret Thatcher (Harriet Walter).
Thatcher and Walden had a lot in common and having both been in Parliament at the same time, they developed mutual respect for one another.
