When the right hon. Gentleman says in his statement that, under the Government's proposals, the Secretary of State for Scotland will act on the advice of the proposed Scottish Assembly and its Chief Executive, and then says in the next breath that he will reserve the right to overrule those recommendations when they involve unacceptable repercussions for the United Kingdom as a whole, is he not postulating a constitutional formula which is bound to plunge this country into almost Permanent Constitutional Crisis and lead to the break-up of the United Kingdom?

The House is going to vote potentially to enshrine in our national political life the recipe for a Permanent Constitutional Crisis.
