Will my hon. Friend agree that all treaties involve a pooling of sovereignty? We gave up immense sovereignty when we joined the United Nations
and NATO, membership of which we would never dream of renouncing. The European Court exists to enforce treaty rights, including obligations on members. Does he recall probably the most important case there of modern times, when the British Government took the European Central Bank there to assert our treaty rights so that the City of London and our financial services industry could have a passport to financial services in the eurozone? It was worth thousands of jobs and showed the benefit of the Court in upholding treaty rights, including the most important treaty rights of the UK.
