The powers, functions and duties of prior presidential offices, as well as their relation with the Prime Minister of France and government of France, have over time differed with the various constitutional documents since the French Second Republic. The President of the French Republic is also the "ex officio" Co-Prince of Andorra, Grand Master of the Legion of Honour and of the National Order of Merit. The officeholder is also honorary proto-canon of the Archbasilica of Saint John Lateran in Rome (although some have rejected the title in the past).
