HC Deb 18 November 1981 vol 13 c157W
Mr. Adley

asked the Chancellor of the Exchequer if he will regard the sums involved in the provision of indemnities to private sector financiers against future cancellation of projects such as the Channel tunnel as not adding to the public sector borrowing requirement.

Mr. Brittan

When the Government guarantee borrowing by a private sector institution the PSBR is affected only if and when the guarantee is called. Guarantee borrowing by a public sector body scores when the borrowing takes place.
