That’s a breathtakingly arrogant assertion. The UK and it’s constituent countries have a 2,000 year history. England invented parliamentary government—it eased gently into democracy several hundred years ago, whereas on most of the continent, democracy had to be achieved through violent revolution. Much of the EU didn’t even achieve democracy until the 20th century. It invented many of the concepts of legal rights that are encoded in law across the world. Many countries around the world have language in their constitutions that traces its origins back to the 800 year old Magna Carta. Countries that use British law account for 40% of world GDP. English speaking countries account for a quarter of the world’s GDP. The EU is a tiny blip in British history.
