this is from Wikipedia:
Parliamentary opposition is a form of political opposition to a designated government, particularly in a Westminster-based parliamentary system. Note that this article uses the term government as it is used in Parliamentary systems, i.e. meaning the administration or the cabinet rather than the state.
In First Past the Post assemblies, where the tendency to gravitate into two major parties or party groupings operates strongly, government and opposition roles can go to the two main groupings serially in alternation. In this context, the opposition forms a recognized, even semi-official “government-in-waiting”. Its “opposing” can degenerate into a charade pending the eventual exchange of roles and occupation, or reoccupation, of the Treasury benches.
The more proportional a representative system, the greater the likelihood of multiple political parties appearing in the parliamentary debating chamber. Such systems can foster multiple “opposition” parties which may have little in common and minimal desire to form a united bloc opposed to the government of the day.
Some well-organized democracies, dominated long-term by a single faction, reduce their parliamentary opposition to tokenism. Singapore exemplifies a case of a numerically weak opposition; South Africa under the apartheid regime maintained a long-term imbalance in the parliament. In some cases tame “opposition” parties are created by the governing groups in order to create an impression of democratic debate.
By their very presence in the debating chamber, parliamentary oppositions recognize the legitimacy of the system of politics, and thus may share many of the views of the government. The opposition in such cases can justly claim the title of His/Her Majesty’s Loyal Opposition.
The title of “Official Opposition” usually goes to the largest of the parties sitting in opposition with its leader being given the title “Leader of the Opposition”.
That highlighted line is worrisome in the light of our current situation. On another blog a statement was made about the opposition was there not just as place holders but as a dynamic part of the governmental process. The opposition was there as a watch-dog to highlight the inadequacies of a particular policy or to make known a decision that was not in the best interest of the populace. However if the “opposition” is just a group waiting for their turn on the swing, then one must question the motives of these individuals and be wary of exchanging one dictator for another.
