On top of all the political difficulties getting the UK Parliament to pass legislation for a Brexit. Nicola Sturgeon pointed out Scotland has a de facto veto and said she’ll call on the Scottish Parliament to use it if necessary. Holyrood probably doesn’t have enough pro-Brexit MSPs to make a reservation for brunch, so that will be an easy pass.
Technically, this wouldn’t actually stop Brexit but it would mean all EU laws would continue to apply in Scotland, and make Brexit pretty much pointless. Immigrants could still come to England via Scotland, products would still have to conform to EU safety standards to be sold in Scotland, etc.
Essentially it means no Brexit without Disunion.
