National Service Scheme (Review) 47. Mr. A. R. W. Low asked the Minister of Defence whether he has now completed his review of the National Service Scheme; and if he will make a statement. Mr. Shinwell The practical working of the National Service Act is constantly under review to ensure that it meets the needs of the Services as efficiently as possible. Mr. Low Will the right hon. Gentleman tell the House whether he is considering a system whereby men with National Service liability are allowed to volunteer for a period other than 18 months, with altered obligations, very much in the way which already applies to the Royal Air Force? Mr. Shinwell The idea has been projected, but there is no settlement on these matters as yet.
