For 68 years Queen Elizabeth II has been a constant in post-war Britain. Central to her success is her 73-year marriage to the Duke of Edinburgh, Prince Philip. Yet this royal love story has not always been the stuff of fairy tales.
The Queen's role of wife, mother, sister and grandmother has often placed her in direct conflict with her role as head of state. It is a battle with deep roots in the story of the Windsor dynasty who have survived two world wars, and weathered the 1936 abdication crisis and numerous scandals and tragedies of the 20th century.
Using recently de-classified documents and letters, and personal testimony, this film examines the many pressures faced by Elizabeth and her husband. From Philip abandoning his high-flying naval career, and his battles with the Palace old guard, to Charles being bullied at school, and her sister Princess Margaret's turbulent love life - this film examines the key personal events that have shaped the Queen's reign, asking how high a price has Elizabeth paid for trying to balance the twin pressures of Crown and Family?
The Queen: Love, Honour and The Crown airs Sunday 21st March at 9pm on Channel 4.
