I would not be against a windfall tax on the pertro companies.
That could easily compensate for the 10 p cut in fuel duty.
In case you hadn't noticed, but diesel is up something like 57p/l, or roughly a third in the last 6 months or so. And petrol is up about 35 p/l So of course people are cutting back. With a big increase in electricity and gas prices with winter approaching, what else would you expect.
Perhaps you are comfortably off, so do give a monkey's about those less well off than yourself?
