Tax law is interesting
Interesting thing tax law.
The government will of course bow to the EU. And break the law in doing so.
See, under UK law (that EVERYONE IS SUBJECT TO, including the government) you can't do this. In fact, there are many taxes that are collected illegally in this country.
The law states that you may only collect enough taxes to govern the country, I.e. you charge even the populace for the costs you incur. Anything else is stealing. You can avoid the stealing charge if you collect taxes in advance then don't use them and as such pay them back.
But as I said, the UK government is not averse to breaking the law (you may remember that signing the lisbon treaty was an act of treason which is still illegal in this country) so we'll see this tax enacted without protest. Certainly any protest from the populace they represent will go ignored.
