Channel 4 are presnting an engrossing drama depicting the professional relationship that evolved between Mrs Thatcher the politician and  Brian Walden the labour MP turned television interviewer.

The two lead actors Steve Coogan and Harriet Walter are excellent at showing the  friendly dimension to the relationship that turned sour under media pressure.

David Freeman talked to the actress Harriet Walter when her autobiography 'Other People's Shoes' was published in 2003.
