§ 13. Mr. Farrasked the Chancellor of the Exchequer what is his latest estimate of the total revenue yield from the use of derv in the current financial year, taking into account increased usage.
§ Sir Geoffrey HoweAbout £900 million.
§ Mr. FarrAs a diesel-engined vehicle is recognised as being a much more efficient converter of fuel, will my right hon. and learned Friend investigate a policy of reducing, or at any rate stabilising, the level of revenue that he receives from dery to stimulate increased usage?
§ Sir Geoffrey HoweThat is one factor to be taken into account. My hon. Friend will recollect that, in my first Budget, I removed the differential which at that time operated against derv and in favour of petrol.
