The Local Government Act 1972 is a key piece of legislation in the United Kingdom that reformed local government structures in England and Wales. It established a system of local councils, defining their powers and responsibilities, and aimed to improve local governance by creating a more efficient administrative framework. This Act introduced the concept of unitary authorities and reorganized local government into two tiers: county councils and district councils. It also provided guidelines for local elections, financial management, and the delivery of public services, ensuring that local authorities could better serve their communities.
