She'd never have allowed us to become part of the EU superstate either.Thatcher never would've held the referendum and would never leave the EEA, she spent too much time setting it up. I also think that Thatcher would've understood the importance of the UK standing with and supporting the former Eastern Bloc members.
I also doubt she would have been much of a fan of the restrictions in trade outside the EU either - it's hardly the low-regulation, free trade union we signed up for.
