Might I ask three reasonably short supplementaries in one? Can my right hon. Friend consider having some more thorough investigation made, possibly by someone independent of the Command, of this question of underemployment at G.H.Q., M.E.L.F.; secondly, when he refers to the deferment of individuals, will he bear in mind that it is, in fact, done on a group basis, en bloc, several hundreds at a time; and, thirdly, will he always bear in mind that the phrase to which this House assented was "operationally vital" and not merely "administratively convenient"?
