Does the hon. Gentleman accept that it is a question not just of critical mass—as I tried to explain to my hon. Friend the Member for Gloucester (Mr. French)—but of the nature of the loan book? A converting society will, of necessity—even after the Bill is passed—have a loan book comprising 75 per cent. loans secured on residential property. A high street bank has an entirely different loan book. Institutions require some transitional protection when changing from the loan books that they had as societies to the loan books that they will need as banks.
