§ Mr. EnnalsThe contribution review for 1977–78 resulted in increases in the floor and ceiling for class 1 and 4 contribution liability, but no change in the rates of contribution except for class 2 and 3. In commending the contributions order to the House on 11th January 1977—[Vol. 923, c. 1346–55]—I explained the national insurance arguments against reducing contributions in that year only to raise them for the start of new pensions in April 1978, the need to build up the National Insurance Fund in relation to 275W its benefit commitments, and the need to take into account the possibility of sharper than previous fluctuations in the economic factors affecting benefit expenditure. I also explained that although national insurance is a self-contained system its impact could not be considered in isolation from the needs of the economy as a whole.
