a colloquial term for notices of motions given by a member for debate "on an early day" but for which no date has been fixed. Few are actually debated. Generally, EDMs are a way by which members can put on record their opinion on a subject and canvass support for it from fellow-members.
EDMs are motions that are rarely debated but which are useful for raising awareness about a particular issue. One or more MPs put forward the motion, and other MPs who agree with it can add their name to it in support. Christian Aid only encourages the signing of cross party EDMs. Ministers, Junior Ministers and Shadow Cabinet Ministers do not sign EDMs.
Early day motion is a phrase used in the Westminster system for motions tabled by Members of Parliament for debate "on an early day". They are only very rarely debated on the floor of the Chamber of the House. EDMs remain open for signature for the duration of the parliamentary session.
