HC Deb 13 December 1971 vol 828 c33W
Mr. Moyle

asked the Chancellor of the Exchequer what is the increase in the standard rate of income tax necessary in order to increase the state retirement pension by £ 1 for a single person with consequential changes in the rate for a married couple.

Mr. Patrick Jenkin

If the increase were confined to retirement pensions, about 2p. If other benefits such as widows' pensions and supplementary pensions were given matching increases, the standard rate of income tax would have to go up by 3¾p.
