What is Parliamentary Sovereignty

Parliamentary sovereignty can be described as supreme Parliamentary authority. Parliament can make any law that it sees fit and these are enforced by the courts and bodies, such as the police. These laws cannot be overturned by the courts or any other institutions, only Parliament may amend or revoke them. In order to maintain Parliamentary sovereignty, Parliament also cannot bind any future Parliament's.

Some argue that the EU threatens Parliamentary sovereignty, as EU law takes precedent over UK domestic law, however the UK Parliament retain sovereignty as they can exercise thier right to leave the EU at any given time, this has recently been demonstrated by the triggering of Article 50 of the Treaty of Lisbon.
