asked the Chancellor of the Exchequer what is the proportion of the tax contribution to the total revenue contributed in total by the 100 major companies, other than public corporations, in the United Kingdom.

The available information relates to corporation tax analysed by the size of taxable profits. The group with the largest taxable profits, that is profits exceeding £5 million, contains rather over 100 companies which contribute nearly 40 per cent. of the yield of corporation tax.
