Admittedly, I don’t know much about Brexit, but from what I have been exposed to, it seems like a decisively economical and political impairment that made travel and business with the rest of Europe more difficult and costly. Since it is so highly criticized as a terrible move, why doesn’t the UK just rejoin the EU?
They probably wouldn’t force schengen as we’re in a common travel area with Ireland who aren’t in Schengen so they’d have to force in on them too.
