At the meetings of the cabinet the Prime Minister as chairman is no doubt merely primus inter pares. His opinion carries peculiar weight with his colleagues mainly by the force it derives from his character, ability, experience and reputation; but apart from cabinet meetings he has an authority that is real, though not always the same or easy to define.

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]

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.

The extent to which a Prime Minister actually supervises and controls the several departments must, of course, vary in different cabinets. One cannot read the memoirs of Sir Robert Peel without seeing how closely he watched, and how much he guided, every department of the government.[70:1] A score of years later we find Lord Palmerston lamenting that when able men fill every post it is impossible for the Prime Minister to exercise the same decisive influence on public policy;[70:2] and recently Lord Rosebery has told us that owing to the widening of the activity of the government no Premier could, at the present day, exert the control that Peel had over the various branches of the public service.[70:3] It is certain that a Prime Minister cannot maintain such a control if his time is taken up by the conduct of a special department; and this, combined with some natural recklessness in speech, accounts for the strange ignorance that Lord Salisbury displayed at times about the details of administration, as in the case when he excused the lack of military preparation for the South African War on the ground that the Boers had misled the British War Office by smuggling guns into the country in locomotives and munitions of war in pianos.[70:4] It has been usual, therefore, for the Prime Minister to take the office of First Lord of the Treasury, which involves very little administrative work, and leaves its occupant free for his more general duties.[70:5]

He Represents the Cabinet.

The Prime Minister stands between the Crown and the cabinet; for although the King may, and sometimes does, communicate with a minister about the affairs relating to his own department, it is the Premier who acts as the connecting link with the cabinet as a whole, and communicates to him their collective opinion. To such an extent is he the representative of the cabinet in its relations to the Crown that whereas the resignation of any other minister creates only a vacancy, the resignation of a Premier dissolves the cabinet altogether; and even when his successor is selected from among his former colleagues, and not another change is made, yet the loss of the Premier involves technically the formation of a new cabinet.

Unless the Prime Minister is a peer he represents the cabinet as a whole in the House of Commons, making there any statements of a general nature, such as relate, for example, to the amount of time the government will need for its measures, or to the question of what bills it will proceed with, and how far the lack of time will compel it to abandon the rest. The other ministers usually speak only about matters in which they are directly concerned. They defend the appropriations, explain the measures, and answer the questions relating to their own departments; but they do not ordinarily take any active part in the discussion of other subjects, unless a debate lasts for two or three days, when one or more of them may be needed. They are, indeed, often so busy in their own rooms at the House that it is not uncommon, when a government measure of second-rate importance is in progress, to see the Treasury Bench entirely deserted except for the minister in charge of the bill. But the Prime Minister must keep a careful watch on the progress of all government measures; and he is expected to speak not only on all general questions, but on all the most important government bills. He can do this, of course, only in the House of which he happens to be a member; and the strength of his all-pervading influence upon the government depends to no slight extent upon the question whether he sits in the Lords or the Commons.

As the House of Commons is the place where the great battles of the parties are fought, a Prime Minister who is a peer is in something of the position of a commander-in-chief who is not present with the forces in the field. He must send his directions from afar, and trust a lieutenant to carry them out. In such a case the leader of the House of Commons stands in something of the position of a deputy premier. He is, of necessity, constantly consulted by his colleagues in the House, and he can, if so disposed, draw into his own hands a part of the authority belonging to the head of the cabinet. As Mr. Gladstone remarked, "The overweight, again, of the House of Commons is apt, other things being equal, to bring its Leader inconveniently near in power to a Prime Minister who is a peer. He can play off the House of Commons against his chief; and instances might be cited, though they are happily most rare, when he has served him very ugly tricks."[72:1] It is certainly true that the Prime Ministers who have most dominated their cabinets, and have had their administrations most fully under their control, have all been in the Commons. It may be added that a high authority has declared that "no administrations are so successful as those where the distance in parliamentary authority, party influence, and popular position, between the Prime Minister and his colleagues in the cabinet, is wide, recognised and decisive."[72:2]
