Treaty of Union 'is a treaty in international law': lawscot.org.uk/members/journa…) The British are forever telling us that the union is a voluntary one, if that is the case, there is nothing to stop us withdrawing from the Treaty of Union. The SNP 'open negotiations on independence'.

Bill Cruickshank The SNP The UK Government will refuse to negotiate.
Leave the offer on the table and go to the EU, UN and nations individually.
Has to be a full-blown international constitutional crisis or the UK will just brass it out.
Ultimate action Revoke the Treaty of Union.
Then its fireworks

Para Handy Bill Cruickshank The SNP Agree with this route,
Forced into the union
Now we need to force our way out of the union
