Motion of no confidence
A motion of no-confidence, alternatively vote of no confidence, or (unsuccessful) confidence motion, is a statement or vote which states that a person in a position of responsibility (government, managerial, etc.) is no longer deemed fit to hold that position, perhaps because they are inadequate in some respect, are failing to carry out obligations, or are making decisions that other members feel detrimental. As a parliamentary motion, it demonstrates to the head of state that the elected parliament no longer has confidence in (one or more members of) the appointed government.
