The right hon. Gentleman seeks to give with one hand and take with the other. With the greatest of diffidence and respect, he is not quite right. The unilateral declaration is not incompatible with international law. It reserves the United Kingdom’s right to take all measures available to it in circumstances where the talks have broken down as a result of a breach of article 5, which is the good faith duty. It reinforces and further stresses the United Kingdom’s right to take measures to withdraw from the arrangements if there is a breach of good faith.
