Re: It is only a draft law
if the UK eliminated the umpteen volumes of exceptions in tax law, they'd probably be able to get more in with a 12.5% tax rate than they do now - and probably net more because they could lay off 2/3 of HMRC staff.
This isn't pie in the sky handwaving. It's been done before. The important thing is to stamp out the plethora of exemptions and loopholes which can be exploited (including the varying rates of VAT, which are a fraudster's wet dream)
