Grousebeater’s Blog on the Union.
An excellent look at the Union of 1707 and what possibilities there are for change. Requires a different mindset perhaps but also I’m sure there are plenty of legal challenges to actions to dissolve the union by any of these means.
Linked in the above article contents but separately linked here for interest is a study of the Union and the articles. (Thanks to Kangaroo! and Caltonjock)
