European Union (Amendment) Bill

From the hon. Gentleman's Jesuit education he will recall the tag, ““Pacta sunt servanda””—treaties must be obeyed. I can give him one example of a treaty which, thank goodness, we have never sought to renegotiate, or allowed any other signatory to renegotiate—the treaty of Utrecht, which gives us sovereignty over Gibraltar. The hon. Gentleman should be careful; treaties need every signatory either to quit the treaty fully or to agree renegotiation. Treaties cannot be renegotiated unilaterally.
