Sadly Norcon is unable to count, and does not know what a "dozen" is.
If he had the wit to look up UK's VAT rates, he would have found:
"Conservative Chancellor Geoffrey Howe increased the standard rate of VAT from 8% to 15% .... The rate remained unchanged until 1991, when Conservative Chancellor Norman Lamont increased it from 15% to 17.5%.
During the 1992 general election the Conservatives promised not to extend the scope of VAT, but, in March 1993, Lamont announced that domestic fuel and power, which had previously been zero-rated, would have VAT levied at 8% from April 1994 and the full 17.5% from April 1995"
Sweetly done
