asked Her Majesty's Government:

Whether, if separate elections are held for more than one vacancy on the same day in the same ward or division of the same local authority or parish council, it is possible for a person to stand in each separate election; and what are the consequences if such a candidate tops the poll in more than one of the elections.[HL7818]

There are no specific rules preventing a person nominating (or being nominated for) each of two or more casual vacancies within the same ward or division at a local government election. However, a successful candidate must make a declaration of which office he is accepting, and the returning officer should be able to declare, applying criteria set out under Section 89 of the Local Government Act 1972, which of the other candidates should fill the remaining vacant offices.
