Using unseen archive footage, new filming and interviews with those closest to the action, Michael Cockerell tells the inside story of the 20 years that took Margaret Thatcher from Commons new girl to her election in 1979 as the first ever female British prime minister.

This acclaimed 1993 BBC documentary coincided with the release of Margaret Thatcher’s book, The Downing Street Years. The series charts her time in office with interviews from both friends and rivals clocking over four hours.
