asked the Secretary of State for Social Services what is the tax threshold for a single person, a married couple, a married couple with one child and a married couple with two children in the tax year 1980–81; whether the invalidity benefit for each of these groupings is above or below the tax threshold; what additional income each of these units claiming (a) invalidity benefit, (b) sickness benefit, and (c) unemployment benefit, needs to make them eligible for tax equivalent to the proposed five point reduction.

I have been asked to reply.I shall let the hon. Member have a reply as soon as possible.
