Queen Elizabeth II is Britain's oldest serving monach. In April 1926, however, at the time of her birth, there was no reason to assume she would one day become Queen. For a portion of her childhood at least, Elizabeth lived the life of a princess, without the scrutiny that would normally attend the upbringing of a future sovereign. This programme, through unique archive footage, reveals glimpses of her early family life. However, what was that childhood life? And how did life change once destiny intervened and her fate as future Queen looked to be sealed? Features exclusive, recently conducted interviews with Hugo Vickers, Sarah Bradford, Countess Mountbatten of Burma, Ingrid Seward and Lady Glenconner.
