asked the Under-Secretary of State for Air why many National Service men are told that if they do not enter into a three-years' engagement they will be obliged to do their National Service with the Army or the Navy.

There is a limited number of vacancies for National Service men in the Royal Air Force and keen competition for them. Men for whom National Service vacancies cannot be found are, if they are suitable, offered Regular engagements, which they often prefer to doing National Service in one of the other Services.
