“Repealing the 1972 Act will make the ­United Kingdom fully sovereign —
in a way that Japan or Switzerland or New Zealand take as read.” –

Japan and New Zealand are geographically and democratically isolated – one a bunch of islands off the Eastern Coast of Asia, with only a country like South Korea in its proximity coming close to sharing its democratical values, the other lying in the middle of the Pacific Ocean, thousands of miles away from any country they might consider joining into an economical/ political association.
