Scotland is still part of the United Kingdom but, under devolution, the Scottish Parliament can make decisions on certain issues without needing approval from the UK Parliament. The UK Parliament in Westminster alone still makes decisions for the whole UK on certain issues.
The Northern Ireland Assembly is the devolved legislature for Northern Ireland. It has the power to make laws in a wide range of areas, including housing, employment, education, health, agriculture and the environment. It meets at Parliament Buildings, Belfast.
