The UK Constitution

Wednesday, 28 January 2026

Basic Principles

Four core principles formed the foundation of the UK constitution:

  1. Parliamentary sovereignty - Parliament is the highest law-making body
  2. Rule of law - No one is above the law
  3. Unitary state - Central government holds ultimate authority
  4. Parliamentary government in a constitutional monarchy - The government is drawn from Parliament and is accountable to it, while the monarch’s powers are largely ceremonial

Parliamentary Sovereignty

Sovereign, nothing sits more powerful than parliament in the UK.

  • Parliament can pass any laws
  • Legislation cannot be overturned by a higher authority
  • No parliament can bind its successors

Therefore, parliament can pass laws on anything.

Rule of Law

  • Ensures state action is limited and responsible
  • No one is above the law
  • Everyone should be equal before the law
  • Is an essential feature of a liberal democracy
  • Has been eroded in recent years - removal of right to trial by jury and double jeopardy
