Closed petition Constitution to prevent ceding sovereignty to foreign powers without referendum

Closed on 13 January 2019

In signing the European Communities Bill in 1972 thus taking us into the EEC without our consent, Edward Heath sacrificed our independence. Thus making the articles on the supremacy of British Parliament only of historical perspective.
He should've had referendum 1st on such constitutional change

In enacting the European Communities Bill through an ordinary vote in the House of Commons, Heath's Government breached the constitutional convention which requires a prior consultation of the people (either by a general election or a referendum) on any measure involving constitutional change.
We need a constitution that is not merely convention, but that is actually written into our law to prevent this happening again.
