§ Mr. Viggersasked the Chancellor of the Exchequer what would be the estimated cost in tax revenue lost of raising the ceiling on the amount of a mortgage for which interest payments are allowable against income for personal taxation from £25,000 to £35,000 outturn prices and at estimated 1983–84 outturn prices.
§ Mr. Ridley[pursuant to his reply, 25 November 1982, c. 541]: Information on which to base a firm estimate is not available, but disregarding any new borrowing that the raising of the limit might generate it seems unlikely that the revenue cost would exceed £100 million at the income levels of either year.
