1. I'm sure it would survive - as said it's become more than just a national flag. probably would become rare in Scotland.
2. I'm confident that the Scots will say no. It would save us from being a one party Tory state this side of the border, but the downside is that we'll have to go on subsidising them.
If the vote is yes can we have verse 6 of the national anthem sung at all future England v Scotland sports fixtures?
Lord grant that Marshal Wade
May by thy mighty aid
Victory bring
May he sedition hush
And like a torrent rush
Rebellious Scots to crush
God save the Queen
