Mr. WILLIAM WHITELEY The numbers of personnel in the Royal Air Force paid for out of Air Votes are set out in a table which, with my hon. Friend's permission, I will circulate in the OFFICIAL REPORT. I am not sure what my hon. Friend means by the annual cost of the service. If he will be so good as to communicate with the Under-Secretary of State for Air, he will endeavour to supply the figures required.
