§ Dr. McDonald
asked the Secretary of State for Social Services what would be the saving to the national insurance fund in 1979–80 if the ceiling on social security contributions were abolished.
§ Mrs. Chalker
On the economic assumptions outlined in the report by the Government Actuary on the draft of the Social Security Benefits Up-rating Order 1979—Cmnd. 7606—if the ceiling on social security contributions was abolished for the whole tax year 1979–80, it is estimated that contributions due to the national insurance fund would in crease by about £500 million—of which about £410 million would be paid within the year and the balance later—with the Treasury supplement going up by £130 million—£110 million.
