HC Deb 13 December 1967 vol 756 c173W
119. Mr. Higgins

asked the Minister of Social Security what she estimates to be the cost to the National Insurance Fund of paying a pension based on that proportion of the retirement or widow's pension. not covered by contributions at the present rates, to those surviving old people excluded from the National Insurance Scheme in 1948.

Mrs. Hart:

National Insurance pensions are not financed in a way which would enable a calculation of this kind to be made. Pensioners and their employers have all contributed different amounts.
