The collective co-ordinating function of the Cabinet is reinforced by the statutory position that all the secretaries of state jointly hold the same office, and can exercise the same powers. This does not, however, apply to the non-secretaries of state in the Cabinet such as the leader of the House of Commons (when such office of Cabinet rank). Technically, therefore, the Cabinet is composed of many more people than legal offices, since the secretary of stateship is actually in commission, as is the position of Lord High Treasurer, with the prime minister and chancellor being the first and second lords of the treasury, respectively.
