§ Mr. OrmeOn the assumptions used in the Government Actuary's Report on the 1978–79 contributions rates (Cmnd. 7036), and that the upper earnings limit for class 4 contributions had been correspondingly raised to £6,800 per year, the additional revenue in 1977–78 would be some £240 million, including for class 1 contributions the national insurance surcharge.
