In the UK, the sovereign power to make law lies with the legislature, which is Parliament. Parliament passes Acts of Parliament, known as primary legislation. The judiciary interprets statutes, the executive introduces laws, and the Law Commission recommends legal reforms. The Monarchy's role is largely ceremonial in this context. 

Key Point: Understanding the separation of powers and the roles of different bodies in the legislative process is fundamental to grasping how laws are created and implemented in the UK.
