31. Mr. Mitchellasked the Secretary of State for War the number of factories, by counties, which, under his scheme of self-defence, have undertaken to provide from their own personnel a certain amount of anti-aircraft defence; whether he is satisfied with the response in each county; and whether there still remain any important industrial centres of any size which are undefended by any such factory armaments or by Air Ministry plans?
§ Mr. Hore-BelishaI cannot, in the public interest, disclose the particulars 1875 asked for, but the response is satisfactory. The general scheme of our air defences as a whole affords a large measure of protection to all vulnerable points.
