Two friends drew my attention to report in The Daily Telegraph about dissension between the Orleanist claimant to the French throne, the de jure King Henri VII, and his second son, Jean, about whether the latter should be, as his father intends, in effect, Regent for his disabled elder brother or whether as he thinks, should suceed to the headship of the House of France upon the present Head's decease. The article can be read at http://www.telegraph.co.uk/news/2016/08/09/pretender-to-frances-non-existent-throne-embroiled-in-succession/
The situation looks rather similar to the Bavarian situation in 1913 when the new Regent, Prince Ludwig, suceeded his father Prince Luitpold as Regent for King Otto, and then assumed the throne as King Ludwig III, although King Otto lived until 1916. Only then did King Ludwig assume sole and undisputed sovereignty over the realm.
