"I don't suppose there's still a Pretender kicking around, is there? France could do worse."
The Duc d'Orleans is not a pretender, but the legitimate heir to the throne of France. And were such throne to still exist, he would be King. But it doesn't, so he's not, although he does have his partisans, and there is a (small) Royalist Party. (In truth, it is a social club for aristos of a certain age.)
I don't think a restoration is on the cards.
Well, that was an interesting half-hour's reading. I didn't know there were any Bourbons left, let alone that there's a Spanish pretender to the French throne as well. What slight knowledge of French history I have is pretty much limited to the period between Henri IV ("Paris vaut bien une Messe" - probably my spelling's wrong) and Louis XIV. I've been reading up on the Affair of the Poisons lately.
