Almost all bills are presented by the government in power. They reflect policy decisions taken in the cabinet at the instigation of government departments that will be responsible for the administration of the decisions when the bills become law. The principal exceptions are Private Bills, which relate solely to some matter of individual, corporate, or local interest, and Private Members' Bills, which are introduced by individual MP's. The manner in which Parliament--generally the House of Commons--controls the government in power emphasizes the difference between the British system and our own. The ultimate control is the power of the House of Commons to pass a resolution of "no confidence" in the government or to reject a proposal which the government considers so vital to its policy that it has made the proposal's passage a "matter of confidence." If such a proposal is rejected, the government is obliged to resign. In addition, there is that very British institution, Question Time. Between 2:30 and 3:30 each afternoon from Monday through Thursday, MP's may question any minister on the work of his department and the Prime Minister on general national policy. The questions range from the trivial to the significant. A query about the heating in a remote Army barracks may be followed by one about progress on the hydrogen bomb. The growth of Question Time as an institution has put a special premium on those ministers or junior ministers best able to parry and riposte. For the opposition can press the minister, and if his original reply is unsatisfactory, the questioner will follow with a supplementary question designed to reveal the minister as incapable and ignorant. The majority of questions are put by the opposition in the hope of focusing public attention on the government's weaknesses. But government Members also put questions dealing with affairs in their constituencies. A number of them also can be counted upon to offer ministers congratulatory queries along the lines "Is the Right Honorable Gentleman aware that his reply will be welcomed by all those ...?" Questions and answers are couched in the glistening phrases of polite debate, but occasionally tempers rise and the Speaker intervenes. Because of the variety of subject matter and the importance of some of the questions, Question Time is an exciting period. It was never more so than in the last administration of Sir Winston Churchill. That Prime Minister, armed with the political experience of fifty years, was a joy to watch in action. One of his last memorable sallies was at the expense of Woodrow Wyatt, an earnest young Labor MP. What plans had the government, Wyatt asked, for evacuating itself from London in the event of atomic attack? Sir Winston regarded him owlishly. "Surely the Honorable Member does not wish me to take the bread out of the mouths of the Soviet secret service," he said.
