The Local Authorities (Elected Mayors)(Elections, Terms of Office and Casual Vacancies)(England) Regulations 2012
Under the Local Government Act 2000 (“the 2000 Act”) a local authority may, or may be required to, hold a referendum on the question of whether it should adopt a mayor and cabinet executive. Where the result of such a referendum is to approve proposals for such arrangements, an election for the return of an elected mayor is required. A local authority may also, if not required to hold a referendum under section 9M or an order made under section 9N resolve, without holding a referendum, to adopt a mayor and cabinet executive.
