Which act expanded the options for local government structure and allowed for elected mayors?

The Localism Act 2011 is recognized for providing increased flexibility and options for local government structure in England, including the provision for elected mayors. This act aimed to empower local communities and councils, giving them greater control over local decisions and encouraging greater public participation in governance.

One of its significant features was the introduction of the option for local authorities to adopt directly elected mayors, enhancing democratic accountability at the local level. The act encouraged areas to explore different governance arrangements tailored to their specific needs and circumstances, thereby reforming the local government landscape.

While other acts might touch on aspects of local governance, the Localism Act 2011 specifically addresses the structural framework for local governments and the introduction of directly elected mayors, making it the most relevant choice in this context.
