Oral Answers to Questions — Aircraft Production. – in the House of Commons at on 17 July 1940.
asked the Parliamentary Secretary to the Ministry of Aircraft Production whether, in view of the recent increase of the Excess Profits Tax to 100 per cent., he intends to continue the special branch known as the Technical Costs Department?
Yes, Sir. The raising of the rate of Excess Profits Tax to 100 per cent. makes it the more necessary to check uneconomical and inefficient production. The work of the Technical Costs Branch, which serves both the Admiralty and the Ministry of Aircraft Production, has been adapted to that end, and its work will be continued.
