Public Expenditure Sir David Price asked the Chancellor of the Exchequer, following his Budget proposals and the Government's expenditure plans for 1987–88, what percentage of the gross domestic product will be represented by public expenditure, taxation and the public sector borrowing requirement, respectively in 1987–88; and how these percentages compare with similar figures for 1978–79. Mr. MacGregor I shall let my hon. Friend have a reply as soon as possible.
