asked the Chancellor of the Exchequer if he will update his Written Answer to the hon. Member for Norfolk, South (Mr. MacGregor) concerning income tax yields, Official Report, 26th January, columns 779–80, so as to include complete figures for 1977–78 and best estimates for 1978–79.

I regret that in the time available it has not been possible to provide the information requested. I will write to the hon. Member.

asked the Chancellor of the Exchequer if he will republish the table contained in the Written Answer to the hon. Member for Blaby concerning income tax yields, Official Report, 15th February, columns 275–6, with the addi- tion of comparable figures for 1977–78 and best estimates for 1978–79.

The figures for 1977–78 and 1978–79 exclude the estimated yields from the first two stages of the switch from child tax allowances and family allowances to child benefit, the inclusion of which would invalidate comparisons with the other columns and with previous years. It follows that in columns (1) and (4) the child tax allowances are those for 1976–77.
