Split Loyalties Gordon?

I blogged recently that if the EU Treaty is agreed then Heads of Government when sitting as "The European Council" are required to owe their primary loyalty must be to the Union and as such their primary aim will be to "promote its values, advance its interests, its objectives, serve its interests."

Now I read at English Democrats that Gordon Brown was one of the Scottish MPs who in 1989 signed the "Scottish Claim of Right". This stated (my emphasis) that ""We, gathered as the
Scottish Constitutional Convention, do hereby acknowledge the sovereign
right of the Scottish people to determine the form of Government best suited to their needs, and do hereby declare and pledge that in all our actions and deliberations their interests shall be paramount. We further declare and pledge that our actions and deliberations shall be directed to the following ends: To agree a scheme for an Assembly or Parliament for Scotland; To mobilise Scottish opinion and ensure the approval of the Scottish people for that scheme; and To assert the right of the Scottish people to secure the implementation of that scheme."

For a man who has made such a big play of his Britishness this pledge should raise eyebrows.
