A second referendum would not solve anything. The original referendum should not have been called by PM Cameron. The core issue is one of national English identity. Scotland has its own Scottish nationalist party. Wales has its own nationalist party. Northern Ireland has two nationalist parties for good measure. But English nationalists have had to take cover in the 'broad church' of the Conservative and Unionist Party, to give it its full title. The trouble is that the English nationalists have always chafed under what they see as the heavy yoke of EU regulations. The 'one nation Tories' / Unionists consider keeping the UK together as an important ideal. The two factions have been fighting within the party for decades. It has now come to a head. PM Johnson is going for a break with the EU 'do or die'. Scotland and NI did not have a majority for leaving however. It's a mess. It should not have happened. The UK is not Switzerland, it is a representative democracy, where Parliament is sovereign. As an unintended consequence the UK could break up in the coming years.
