HC Deb 05 March 1981 vol 1000 c172W
Mr. Trotter

asked the Chancellor of the Exchequer to what figure the present limit of mortgage for which interest is allowed against income tax would have to be raised if the limit were to be increased in line with the fall in the value of £ sterling since the current limit was introduced; and what is his estimate of the cost to the Exchequer of raising the limit to this figure.

Mr. Peter Rees

I shall let my hon. Friend have a reply as soon as possible.
