I strongly suspect that most people in the rest of the EU are crossing their fingers against the possibility that the UK might change its mind and stay in. That's among those who are particularly interested in the whole thing. A silent majority - rather similar to what was revealed in a study that found that a large majority of Tories would be happy to see the back of Scotland and Northern Ireland if that would mean that Brexit went ahead. So much for Theresa May's "our precious union".

Large majorities of English Tory voters would be willing to support Scottish independence (79 percent) or even the undoing of the Northern Ireland peace process (75 percent) as “worth it” to “take back control” from the European Union, new research from the Universities of Edinburgh and Cardiff has suggested.
