Say Germany wins WW2 and France continues to be a Nazi puppet state. Whatever scenario there is for that, I don't really care about. But with a continued Vichy France, who would succeed Pétain?
I understand Pierre Laval would be the obvious possibility, but he was already 62 when he was executed in 1945 so I think he'd not live too much longer afterward anyway (and even more doubtfully to reign after Pétain, who lived until 1951), so I would generally like the next possibility.
