What a sack of shit. Take 10p tax off a litre of petrol.

I love a well reasoned argument!
When the price of petrol was last rising, it was made clear that the government was gaining massive, unplanned for, income. The increase in price increases Corporation Tax & VAT take by the government. The fuel duty is the only 'fixed cost' in the price of petrol at the pumps.
If David Cameron states that this can be reduced (when the price of fuel is high) then I will accept that.

Probably it will last no longer than 7 May if they get elected, which of course they won't.
By 7th May they would not yet be in Government, so it could not be introduced in time to end then.
Do you think before posting?
