Cabinet collective responsibility, also known as collective ministerial responsibility, is a constitutional convention in parliamentary systems and a cornerstone of the Westminster system of government, that members of the cabinet must publicly support all governmental decisions made in Cabinet, even if they do not privately agree with them. This support includes voting for the government in the legislature. This convention formed in the 19th century in the United Kingdom. Some political parties, most commonly communist, apply a similar convention of democratic centralism to their central committee.
If a member of the Cabinet wishes to openly object to a Cabinet decision then they are obliged to resign from their position in the Cabinet.
