Ian Douglas Campbell succeeded his cousin to become 11th Duke of Argyll in 1949. With the dukedom came other honours: Hereditary Master of the Royal Household, Scotland; Hereditary High Sheriff of the County of Argyll; Admiral of the Western Coast and Isles; Keeper of the Great Seal of Scotland. The Duke’s many official duties ensured that proceedings relating to his divorce from his third duchess, Margaret, in 1963 were a matter of public interest. The sensational revelations in court, involving prominent figures on both sides of the Atlantic, became the diet of the popular press for many weeks. Like the contemporaneous Profumo affair at Westminster, the Argyll divorce heralded the dawn of the permissive sixties. This is a study for a full-length portrait of the Duke.
