The treaty of Rome was an agreement between the original members. Heath said that the referendum back in 75 was about jobs and trade and had nothing to do with losing sovereignty. He lied to the British public. It is something that Prime Ministers quite often do, before referendums about the EU. Heath knew that our entry to the EU, would make us lose sovereignty, but he did everything to hide it from the electorate. That has been proven. There are papers that have come to light, that show our entry to the EU, was done by a huge deception. The first chance we had to put right those lies, we took.
