In a
parliamentary democracy 'confidence and supply' are required for a
government to hold power. A 'confidence and supply agreement' is an agreement that a minor party or independent member of parliament will support the government in
motions of confidence and
appropriation (supply) votes.
Confidence
Main articles: Motion of Confidence,
Motion of no confidence
In most democracies, members of a
parliament can propose a Motion of Confidence or Motion of No Confidence in the government or executive. The results of such motions show how much support the government currently has in parliament. Should a motion of confidence fail, or a motion of no confidence pass, the government will usually either resign and allow other politicians to form a new government, or call an
election.
Supply
Main articles: Appropriation bill,
Loss of Supply
Most democracies require an
Appropriation bill or something similar to be passed by parliament in order for a government to receive money to enact its policies. If an appropriation bill fails, the government loses control of the money supply, and is therefore virtually powerless. In effect, the failure of a supply bill has the same effect as the failure of a confidence motion. In early modern
England, the withholding of funds was one of
parliament's few ways of controlling the
monarch.
