§ 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 allowance for which interest payments are allowable against income for personal taxation from £25,030 to: (a) £50.000 and (b) £60,000, both at 1980–81 outturn prices and at estimated 1981–82 outturn prices.
§ Mr. Peter ReesI regret that the information on which to base a firm estimate is not available, but disregarding any new lending that the raising of the limit might generate ii seems that the cost in either case would not exceed £25 million in 1980–81.
