Claims that 54 out of 1000 is 54% may be just the tip of the iceberg of sheer incompetence, a leading Tory worrier claimed last night.
If the Conservative Party wins the next election, more complicated sums will have to be done, possibly including multiplication, division and lots and lots of subtraction.
A defender of the Conservative mathematics department explained to this newspaper:
"Shifting the decimal point in the wrong direction can make a large difference in any number.
Say the National Debt is £1000 billion, shifting it one place to the right makes it £10,000 billion, or ten trillion pounds, which is more money than there is in the whole world."
It is feared that VAT, currently at 17.5%, could be written down as 175% in Tory chancellor George Osborne's papers somewhere.
A Tory supporter told this newspaper: "This is an indictment of how the standards in the country's exclusive fee paying schools have deteriorated over the last 15 years under this incompetent Labour government."
