At the moment, the Union of England and Scotland, Wales, and Northern Ireland seems to be under great strain. Many Scots want independence from England. Many English want Scotland to have independence or want England to become independent. The United Kingdom seems to be a Disunited Kingdom.
We need a referendum throughout the United Kingdom on this subject, asking all British voters if they want (a) the Union to be dissolved, or (b) the Union to continue and stay in existence (with or without modifications, including the establishment of an English Parliament). This will, hopefully, quash once and for all the nationalist voices in all countries of the United Kingdom who want independence.
We are better together than we are apart!
