§ Mr. John Hallasked the Chancellor of the Exchequer how much higher revenue from taxation and National Insurance contributions will be in 1968– 69 than if the rates and forms of taxation and contribution prevailing on 16th October, 1964 had remained unaltered; how much of this arises from charges falling directly on industry; and whether he will list the changes announced since 16th October, 1964, given in each case the estimated yield of the change in 1968– 69 and the additional charge directly upon industry.
§ Mr. Roy Jenkins:I cannot anticipate the estimates of taxation for 1968– 69 which will appear in the Financial Statement. Moreover, since it is not possible to say how the economy would have developed on certain hypothetical assumptions no estimate can be made of what 315W would now be the yield of the taxes and National Insurance contributions at the rates applying at that time if those measures had not been taken.
