  Courtship and marriage
  In the 1950s Margaretha had a relationship with Robin Douglas-Home, a Scottish aristocrat and the nephew of the future Prime Minister of the United Kingdom Alec Douglas-Home. He came to visit her in Sweden, but they never married. There was speculation in the press that this was due to Sibylla forbidding the match, but Margaretha's nanny and confidante Ingrid Björnberg states categorically in her memoirs that the breakup between the two was caused by Margaretha's reluctance to enter into an engagement with Douglas-Home.
  She met her future husband, the businessman John Ambler, ten years her elder, at a dinner party in the United Kingdom in 1963 and their engagement was announced on 28 February 1964. They were married on 30 June 1964, in Gärdslösa Church, on the island of Öland. The Princess wore a wedding gown from the Stockholm couture school, Märthaskolan, where she had previously been a student, and a traditional wedding crown from Öland.
