HC Deb 27 March 1969 vol 780 c355W
Sir B. Rhys Williams

asked the Chancellor of the Exchequer what number of people in receipt of earned income incur liability for Income Tax at an effective rate of 6s. 5d. in the £ sterling on their marginal earnings; and what proportion this represents of the total number of people in receipt of earned income.

Mr. Harold Lever

About 13½ million, counting earning wives separately from their husbands, or nearly three-fifths of the total number with earned income.
