In the first place the Prime Minister has a considerable patronage at his disposal. Subject to the limitations imposed by political exigencies, he virtually appoints all the members of the ministry. The ecclesiastical offices also, from the bishoprics to the larger livings in the gift of the Crown, are bestowed on his recommendation; and so as a rule are peerages and other honours; and he has a general presumptive right to nominate to any new office that is established under the Crown.[69:1] [Sidenote: His Supervision.] He is both an official channel of communication and an informal mediator. The duties of the Prime Minister, if one may use the expression, surround the cabinet. He stands in a sense between it and all the other forces in the state with which it may come into contact, and he even stands between it and its own members. Matters of exceptional importance ought to be brought to his attention before they are discussed in the cabinet; and any differences that may arise between any two ministers, or the departments over which they preside, should be submitted to him for decision, subject, of course, to a possible appeal to the cabinet. He is supposed to exercise a general supervision over all the departments. Nothing of moment that relates to the general policy of the government, or that may affect seriously the efficiency of the service, ought to be transacted without his advice. He has a right to expect, for example, to be consulted about the filling of the highest posts in the permanent civil service.[69:2] All this is true of every branch of the government, but the foreign relations of the country are subject to his oversight in a peculiar degree, for he is supposed to see all the important despatches before they are sent, and be kept constantly informed by the Foreign Secretary of the state of relations with other powers.
