§ Mr. Norman Lamont[holding answer 8 December 1988]: Available information is given in the table. Estimates are based on a projection of the 1985–86 survey of personal incomes and are provisional. The base for the comparison is the indexed income tax regime for 1989–90 shown in table 4.1 of the Autumn Statement. Further 28W information could be provided only at disproportionate cost. The estimates do not allow for any behavioural effects and exclude the effect of the changes on the yield of capital gains tax.
