asked the Chancellor of the Exchequer what has been the increase in income tax and national insurance contributions as a proportion of personal income for those on average earnings or less, since 1978–79 to 1982–83.

These increases include a 2¼ point increase in national insurance contributions, off-set for some taxpayers by a reduction in their average rate of income tax.
