HC Deb 13 July 1938 vol 338 cc1320-1
60. Mr. Davidson

asked the Secretary of State for Air the total expenditure, up to date, on the construction of the London air-balloon barrage system?

Sir K. Wood

I regret that it would not be in the public interest to give any precise figures such as the hon. Member asks for, but he will find such information as can be made available on this subject on pages 88 and 89 of Air Estimates for 1938.

Mr. Davidson

While recognising the Minister's reply to be in order so far as he is concerned, may I ask him whether he can assure the House that the expenditure up to date is not entirely outwith the expenditure that he anticipated on this system?

Sir K. Wood

I shall have to think over that question.
