Brexit will bring the decision making closer to the British people and will preserve the British nation.
Ignorant rubbish; the opposite is true. There's no such thing as "The British nation". Seriously.
As a
starting point, it is "The United Kingdom of Great Britain and Northern Ireland". Great Britain is a geographical term, and contains Scotland plus Wales plus England. Scotland has its own independent parliament and legal system, e.g. trials can result in
three verdicts: guilty, not guilty, not proven. So does N Ireland. And I'm not even going to try and describe the status of The Isle of Man and the Channel Islands. For more information, see the very amusing and accurate 5 minute video at
Scotland had an independence referendum two years ago, and narrowly rejected independence largely because it couldn't stay in the EU. Now they want a new referendum on the basis that the last one was under false pretenses. N Ireland may well want to stay in the EU, and rejoin Eire. (And I'm not going to discuss Wales, just because)
In other words, Brexit brings the distinct possibility that the UK will split into three: England+Wales, Scotland, N Ireland.
