Company Cars Mr. Austin Mitchell To ask the Prime Minister whether the Government will introduce legislation to (a) disallow business expenditure on the supply or running costs of passenger cars other than light vans as a business expense and (b) charge the full cost of such vehicles to the keeper for income tax purposes; and if she will provide an estimate of the revenue yield in each case. The Prime Minister I have noted the hon. Member's suggestion. The detailed information needed to give estimates of yield is not available.
