To ask the Chancellor of the Exchequer what proportion of non-North sea money, gross domestic product, non-North sea taxes, national insurance contributions and the poll tax represented in 1989–90; and what is the planned proportion in 1990–91.

It is estimated that non-North sea taxes, national insurance contributions and community charge in 1989–90 amounted to 36¾ per cent. of non-North sea GDP (adjusted to remove the distortion due to the abolition of domestic rates). The Budget forecast for the comparable figure in 1990–91 is 37 per cent.
