Well, my hon. Friend will know that as an Attorney General I simply could not give countenance to the idea that this country would break its international legal obligations. As I have pointed out to the House, there is a right for the United Kingdom to terminate this agreement. If fundamental circumstances change, in the view of the United Kingdom, it would attempt to resolve the matter within the joint committee and it would attempt to resolve it politically, but if, ultimately, with the sovereign right of this House and of the British Government at the time, the United Kingdom took the view that those fundamental circumstances had indeed changed, it would have an undoubted legal right to withdrawal from any treaty.

Let us be clear about these kinds of absolute interpretations of black-letter text. A sovereign state has the right to withdraw if a treaty is no longer compatible with its fundamental interests or, to put it a different way, if fundamental circumstances have changed. I would say that apart from that, of course this country could resile from its commitments, but it would be unwise and it would not be in the tradition of this country to do so. In those circumstances, it is perfectly true that the only remedies the Union would have would be to take countermeasures, and no doubt it would pollute the atmosphere for fruitful relationships between us, which is precisely why this country will never do it, and neither would the European Union.
