Not sure about that. I remember it being mentioned that Question Time featured the Iraq War every single episode from 2003 for five years or so. Only the Northern Rock crisis of 2007 started to supersede it in the news. So Brexit still has a while to go to beat the Iraq War as a long running story.
Personally I think the best solution would be Scotland, England, Wales and United Ireland as independent countries, each as members of the EU, and in a British Isles Cooperative Federation. Problem solved.
