The Swedish Marshal of the Realm (i.e. Lord Chamberlain), Svante Lindqvist, has announced that Christopher O’Neill, who will marry Princess Madeleine on 8 June, will receive no title by virtue of his marriage and remain simply Mr Christopher O’Neill.
The reason given for this is a policy of the royal house’s that a member of the royal house ought to be a Swedish citizen and ought not occupy a position of responsibility in business.
As Christopher O’Neill intends to remain an American citizen (and I suppose also a British subject) and continue his business career he cannot bear the title of HRH Prince of Sweden or Duke of Helsingia and Gastricia, the royal court states, adding that he has consequently respectfully requested to be allowed to remain a private citizen.
The King of Sweden’s lawyer, Axel Calissendorff, recently stated that Mr O’Neill in order to become duke or prince had to become a Swedish citizen, which Calissendorff thought would be possible while at the same time retaining his American and British passports. Apparently Christopher O’Neill preferred not to pursue such a course.
When Princess Madeleine became engaged to Jonas Bergström, in 2009 it was announced that he would become Duke of Helsinga and Gastricia, the two dukedoms held by Princess Madeleine.
As Princess Madeleine, unlike her aunts, has full succession rights to the throne she will retain her title as Her Royal Highness Princess Madeleine of Sweden, Duchess of Helsinga and Gastricia.
