Personally, I think this conspiracy theory is rather ridiculous. I used to work for a charity and they have to be tightly regulated. The idea that a small Uk charity has the time and resource to manipulate the british government and try to build an EU state doesn’t makes no sense to me. I did a bit of research and found ‘key facts’ on their website http://www.commonpurpose.org.uk/aboutus/keyfacts.aspx
I agree with previous comment- if they were that powerful then why havent they taken over the world already?
