My parents voted in the referendum to join the Common Market, I've no idea how they voted,
No they didn’t - the 1975 referendum was to remain in the EEC.
There was no vote in the U.K. to set up a European Parliament
The EP was set up in 1952 - 21 years before the UK joined the EEC.
There was also no vote to agree this.
Yes there was - UK MPs ratified the Maastricht Treaty.
The accounts of the EU Governmental departments have never been signed off by a professional accounting company.
The EU accounts are audited and signed off every year by the ECA (which is described as independent of the Commission).
Same as UK government accounts are audited by the NAO - unless you also think that “The corruption in the UK Government is too big and too toxic for any reputable company to get involved with“?
The corruption in the EU Government is too big and too toxic
Yet they caught up with Farage and the other UKIP MEPs’ corrupt misuse of EU funds.
