I've looked through the Local Government Act 1972 and can find no reference to the parish council being "required to report to the electorate on their tenure" or that there is a requirement for the parish council to give responses to any issues raised. The Act states that the parish council "may" convene a meeting (not must convene it) nor is there any provision for matters to be acted upon by the parish council. The regulations for parish meetings, with or without a parish council, are contained in schedule 12 of the 1972 Act.
