HC Deb 02 February 1983 vol 36 c114W
Sir Brandon Rhys Williams

asked the Chancellor of the Exchequer, further to his reply to the hon. Member for Kensington, 20 January, Official Report, c. 182–83, if he will now estimate the cost of each extra £100 in the possible new tax allowances using the same assumptions as before.

Mr. Ridley

[pursuant to his reply, 26 January 1983, c. 446]: Under the regime described in my hon. Friend's previous question, the cost of an increase of £100 in the tax allowances from the levels specified in my reply would be around £900 million, under the assumption either of independent taxation or joint taxation of investment income.
