I am not sure that the hon. Gentleman's point about the borough engineer's department is correct. On occasion, there is probably a good deal of sucking up among officials in a department who are looking for promotion. It would be wholly wrong to place the police service, which is concerned, above all, with the administration of justice, and which must take a neutral and impartial view, in a stuation in which career prospects depended on how well those involved got on with the political party that happened to be in control of the council.
In all elected bodies, there are bound to be changes in party control. That may not happen as frequently in some authorities as it does in others, but it would be wrong for a man to establish his credentials with a strongly Left-wing authority only to find that it is replaced in the democratic process with a moderately Right-wing party. If the police service was involved in that sort of party political mechanism, it would create problems and tensions for it.
