Separation of Powers
The constitutional principle that the three branches of government — legislature, executive, and judiciary — should be independent of each other to prevent any one branch becoming too powerful.
Real World
The Constitutional Reform Act 2005 removed the Law Lords from the House of Lords and created the separate Supreme Court, strengthening the separation between the judiciary and the legislature.
Exam Focus
Always state that the UK has a partial, not complete, separation of powers — the overlap between executive and legislature is a key evaluative point.
