Debates take place on the floor of the House. Rarely do debates result in decisions, but they can force the government to account for itself and to defend its policies in a public forum. They also enable MPs to test the view of the House over particular issues, which in turn can place considerable pressure on the government. There are many different forms of debates, most notably: main business debates (on legislation), daily adjournment debates, and emergency debates. Emergency debates can be highly significant as they allow MPs to discuss a specific and important issue. A notable example is the emergency debate, which took place on 18 March 2003, on the proposed war in Iraq. MPs can also table Early Day Motions, which are technically calls for debate but which very rarely lead to one, being used far more often to raise a matter of general concern or to launch a campaign on a specific issue.
