Worth also noting, is the extent of power granted to those who don't agree with the Prime Minister. > the commons may revoke its confidence in an incumbent prime minister and Cabinet or caucus revolts can quickly bring down a serving premier and even mere threats of such action can persuade and/or compel a prime minister to resign his post, as happened with Jean Chrétien. > The Reform Act of 2014 codifies the process by which a caucus may trigger a party leadership review and, if necessary, choose an interim leader. > Either the sovereign or his or her viceroy may oppose the prime minister's will in extreme, crisis situations. Also what happens if the ruling party does not have a majority and they lose the coalition that gives them enough seats to rule?
