The Single Market is not a version of Pettycoat Lane writ large as Remainers like to promote. It is not really a market at all – it is a Single Regulatory Regime that comes with several sneaky political ‘add ons’ to ensure the EU remains in control.
- Uncontrolled migration from EU,
- submit to the European Court of Justice,
- Supremacy of EU law
- accept all EU standards even when not applicable to UK.
These are euphemistically called the ‘Four Freedoms’ by the EU. They are in fact chains to bind a country into subservience to the EU.
USA, Australia, New Zealand, China, India etc are not in the Single market and have no problems whatsoever trading with the EU.
