Background
Westminster is the central London district containing the Houses of Parliament, Downing Street, and the Major offices of the UK Government. As a metonym, it refers to the UK Parliament and the political class that operates around it. The Palace of Westminster houses both the House of Commons and the House of Lords and has served as the seat of Parliament since the thirteenth century.
In the context of devolution, Westminster is used as shorthand for the reserved powers held by the UK Government as distinct from those exercised by Holyrood, the Senedd, or Stormont. Scottish and Welsh political debate regularly frames issues in terms of what decisions are made at Westminster versus what falls within the devolved legislatures. The 2026 Holyrood and Senedd elections are partly shaped by each party's relationship to Westminster and the UK-wide political settlement.
Westminster politics directly affects the devolved nations through the Barnett formula, which determines block grant funding for Scotland, Wales, and Northern Ireland based on spending decisions made for England. UK-wide economic policy, defence, immigration, and foreign affairs all remain reserved to Westminster, making its decisions a constant backdrop to devolved election campaigns.
