HC Deb 22 February 1980 vol 979 c640W
Mr. Denzil Davies

asked the Chancellor of the Exchequer how much additional revenue could be raised by abolishing the income tax charge of 25 per cent. on the first £750 of taxable income.

Sir Geoffrey Howe

[pursuant to his reply, 25 February 1980]: About £895 million in a full year at 1979–80 income levels, if the basic rate of 30 per cent. replaces the lower rate of 25 per cent.
