The term "Cabinet" first appears after the Revolutionary Settlement to describe those ministers who conferred privately with the sovereign. The growth of the Cabinet met with widespread complaint and opposition because its meetings were often held in secret and it excluded the ancient Privy Council (of which the Cabinet is formally a committee) from the sovereign's circle of advisers, reducing it to an honorary body. The early Cabinet, like that of today, included the Treasurer and other department heads who sat on the Treasury bench. However, it might also include individuals who were not members of Parliament such as household officers (e.g. the Master of the Horse) and members of the royal family. The exclusion of non-members of Parliament from the Cabinet was essential to the development of ministerial accountability and responsibility.
