Northern Ireland is divided into 18 UK Parliament constituencies: 4 borough constituencies in Belfast and 14 county constituencies elsewhere. The Northern Ireland Act 1998 provides that the constituencies for the Northern Ireland Assembly are the same as the constituencies that are used for the United Kingdom Parliament. Parliamentary constituencies are not used for local government, which is instead carried out by 11 district councils.
Constituencies Each constituency returns one Member of Parliament (MP) to the House of Commons at Westminster.
