HC Deb 13 July 1979 vol 970 c305W
Dr. McDonald

asked the Chancellor of the Exchequer how many lone parents benefit from the married man's tax allowance or additional personal allowance in the current tax year.

Mr. Peter Rees

About 425,000 lone parents benefit from the additional personal allowance in 1979–80. I regret that it is not known how many lone parent families benefit from the married man's allowance, but the number is believed to be very small.
