Wales operates under a devolved governance model—sharing power between its own elected legislature and the UK Parliament in London.
Location: Cardiff Bay.
Established: 1999, following a 1997 referendum (50.3% yes).
Composition: 60 Members of the Senedd (MSs), elected via Additional Member System (mix of constituency and regional lists).
Powers (devolved): Health, education, local government, transport, economic development, environment, agriculture, housing, Welsh language, culture, and some taxation (land transaction tax, landfill disposals tax, Welsh rates of income tax).
Location: Westminster, London.
Retained powers (reserved): Foreign policy, defense, national security, immigration, most taxation (income tax, VAT, corporation tax), welfare, criminal justice, broadcasting, energy, equal opportunities.
Welsh representation: 40 MPs elected via first-past-the-post in Welsh constituencies.
The Senedd passes Acts (laws) on devolved matters. UK Parliament legislates on reserved matters—and can legislate on devolved matters with Senedd consent (Sewel Convention). Disputes resolve via Supreme Court. The Welsh Government (executive) is formed from the Senedd's majority party/coalition, led by the First Minister.
Devolution has expanded: Government of Wales Act 1998 → 2006 → Wales Acts 2014, 2017. Each step transferred more powers. The trajectory continues toward a "reserved powers" model (like Scotland), where everything is devolved unless explicitly reserved.
