Amendment

As a bill passes through Parliament, MPs and peers may suggest amendments - or changes - which they believe will improve the quality of the legislation.

Many hundreds of amendments are proposed by members to major bills as they pass through committee stage, report stage and third reading in both Houses of Parliament.

In the end only a handful of amendments will be incorporated into any bill.

The Speaker - or the chairman in the case of standing committees - has the power to select which amendments should be debated.

by-election

A by-election occurs when a seat in the House of Commons becomes vacant during the lifetime of a Parliament (i.e. between general elections) because the sitting MP dies, resigns, is elevated to the peerage, or becomes ineligible to sit for some other reason. If a vacancy occurs when the House is in session, the Chief Whip of the Party that formerly held the seat moves a Motion for a new writ. This leads to the by-election taking place. Prior notice does not have to be given in the Order Paper of the House. There is no time limit in which a new writ has to be issued, although by convention it is usually done within three months of a seat becoming vacant. There have been times when seats have remained empty for more than six months before a by-election was called. The sitting party will obviously choose a time when they feel confident of success. Seats are often left vacant towards the end of a Parliament to be filled at the General Election though this is not always the case and by-elections have sometimes occurred just before the dissolution of Parliament. While a vacancy exists a member of the same party in a neighbouring constituency handles constituency matters. When the new Member is elected in the by-election, all outstanding matters are handed back. Further information can be obtained from factsheet M7 at the UK Parliament site.
