I hope that I have not interrupted my hon. Friend in the middle of his main point. Does it not go even further than he suggests? Some four years ago the House was asked to ratify a previous treaty—the Single European Act. It contained various provisions. One was that the rights of workers would be decided by unanimity. That is what we thought. That is what we were told. But since the treaty has been ratified, other interpretations have been put upon it. Whatever my hon. Friend reads into the treaty that he has been reading today, is there not a grave danger that others might try to take the treaty even further and that, whatever the small print, its interpretation by the European institutions will take us down roads that we have not even thought of?
