Have a look at history, when do seismic events ever happen at an opportune time. The question of independence for Scotland is not for the EU or UK, its solely for the Scots to decide. The Tory right wing have created the situation and the price will be paid for same. Personally in my view its simple, if the UK government try to delay or frustrate a second ref for 4-5 yrs, then the Scottish government should take their democratic mandate and hold the 2nd ref to their own timetable before the end of the 2 yrs and with the full knowledge of the deal which will have been concluded in the next 18 mths for consideration by the the 27 governments, plus the EU Parliament. Then if they win, withdraw their MP`s from Westminster and declare a UDI. That is a perfectly democratic start for any modern nation to begin with.
Seconded. That's pretty much how we did it. https://finland.fi/life-society/finland-celebrates-100-years-of-independence-in-2017/
I recommend skipping the civil war that followed though.
