Since 1997, the central government has handed some of its powers to Wales, Scotland and Northern Ireland. This is called devolution, and the powers are devolved: people there get more say over the things that affect them directly. The Welsh Assembly and the Scottish Parliament have existed since 1999. Northern Ireland has the Northern Ireland Assembly, although it has been suspended several times.
