HC Deb 23 March 1978 vol 946 c740W
Mr. Ovenden

asked the Chancellor of the Exchequer how many lone parents pay investment income surcharge on (a) investment income alone, (b) maintenance alone, and (c) a combination of investment income and maintenance, respectively.

Mr. Robert Sheldon

It is estimated that about 10,000 single parents pay the investment income surcharge. I regret that no more detailed information is available.
