88.Section 28 makes provisions about this. Any person elected as Mayor or an Assembly member must make a declaration of acceptance of office in order to be allowed to act in that office. The declaration must be delivered to the proper officer of the Authority within two months of the date of the election, or else a vacancy will be declared.
89.Section 3(4) enables the Secretary of State to make detailed arrangements in connection with the first ordinary elections. The Secretary of State may also use this order to make provision specifying how, in connection with the first elections, declarations of acceptance of office are to be made and delivered. The order may for example appoint an officer to receive these first declarations.
