HC Deb 15 May 1980 vol 984 c648W
Mr. Ralph Howell

asked the Chancellor of the Exchequer if he will update the reply given to the hon. Member for Norfolk, North, Official Report, 31 July 1978, c. 66, comparing net tax and national insurance liability at different levels of earnings and for different family groups in 1979–80 and 1980–81.

Mr. Peter Rees

The previous answer to my hon. Friend was based on earnings in May 1979, the latest figure then available, to represent earnings in 1978–79. The estimate of average earnings for May 1980, as now calculated, will not be available until mid-August 1980.
