HC Deb 09 December 1981 vol 14 c417W
Mr. Speed

asked the Secretary of State for Defence what has been the total expenditure on the Trident programme up to the most recent convenient date; and what proportion of this has come out of the naval target heading.

Mr. Blaker

[pursuant to his reply, 4 December 1981, c.265]: Estimated expenditure on Trident in financial years 1980–81 and 1981–82 was about £4 million to £5 million and £60 million respectively. Expenditure on Trident to date remains within these estimates. Current expenditure is controlled by the Vote system, not by target heading.
