Not quite, the EEC was but there's always been an element of "ever closer union implied". The EEC didn't have one IRC it might have had a corporate flag, I can't remember
Well Enoch Powell did warn us even some of the Irish agree ...
Enoch Powell was right in his dire warnings about EU
snip "Almost 45 years ago, before Britain made its successful application to join what was then called the Common Market, Powell warned Britons they would lose the power to govern themselves. Equally presciently, from the moment a single currency was mooted, he pointed out that countries joining it would be stripped of their economic sovereignty - and, if it were to function properly, would lose the right to have their governments determine the exact nature of their public spending.
Sounds familiar? Maybe Britain and Ireland should have heeded his timely warning"
