Parliamentary Constituencies Act 1986

The Parliamentary Constituencies Act 1986 is a UK law that establishes how parliamentary boundaries are reviewed and modified. Its purpose is to ensure fair representation by periodically reassessing the size and boundaries of constituencies—geographical areas represented by Members of Parliament (MPs). The Act created a Boundary Commission responsible for recommending changes based on population shifts and other factors, aiming to maintain balanced representation across regions. It provides a structured process to update constituencies, maintaining democratic fairness and reflecting demographic changes over time.
