The statesman sent for by the Crown and intrusted with the formation of a ministry becomes himself the Prime Minister, and selects his colleagues. It may be added, also, that he has virtually power to dismiss a minister; that is, subject to his responsibility to the cabinet as a whole and to Parliament, he can request the Crown to dismiss a colleague--a request which the Crown cannot practically refuse.[56:1] In the selection of the cabinet his choice is, however, decidedly limited both as to persons and offices. In the first place, all the men still in active public life who served in the last cabinet of the party have a claim, a very strong claim, to sit in the new cabinet, and hence it is unusual to discard a man who is willing to return to office.[57:1] This in itself fills a goodly number of the cabinet positions. Then all the prominent leaders in Parliament, and especially in the House of Commons, must be included. In fact, as Mr. Bagehot puts it, the Prime Minister's independent choice extends rather to the division of the cabinet offices than to the choice of cabinet ministers. Still, he has some latitude in regard to the men whom he will admit; especially the younger men, who are appointed to offices in the ministry but not in the cabinet, and this may be a matter of great moment. One cannot tell, for example, how different the history of Parliament in the middle of the century might have been had Peel decided to invite Disraeli to join his ministry in 1841.[57:2] Although the Prime Minister has by no means a free hand in the selection of his colleagues, the task is often extremely difficult and vexatious. It is like that of constructing a figure out of blocks which are too numerous for the purpose, and which are not of shapes to fit perfectly together; for with the selection of the members of the cabinet the difficulties are by no means over. The distribution of the offices among them may raise additional problems. One man will take only a particular office, while others may object to serving if he occupies that post. Where parties are a good deal broken up, or are evenly divided, obstacles like these have sometimes prevented the formation of a cabinet altogether; and there is always some disappointment and consequent discontent on the part of men who thought themselves sufficiently prominent to be admitted to the ministry, and whose chagrin may drive them into an independent attitude.
