Perhaps someone from the Elder Council...like maybe they guy that ordered it (if you didn't kill him, too). But ultimately you have to remember that what happens in faction quests aren't always considered hard cannon, it's primarily the main quests that make it into lore. There are exceptions, and there are rumors of things, but some of those contradict one another. The most likely choice to be emperor next would be either somebody from the Elder Council or which ever General can muster enough forces to take and hold the city - unless the Aldmeri Dominion do something drastic.
