elected as mayor
It is not possible for a councillor to be both a member of an
electoral division or ward in a local authority and the elected
mayor of that local authority.
If a person is standing as a candidate for mayoral and councillor
elections in the same authority taking place at the same time
and is elected to both offices, a casual vacancy for the relevant
division or ward is declared vacant.
If a sitting councillor for an electoral division or ward is elected
as elected mayor of the local authority then a casual vacancy
arises for the ward or division
An elected mayor may not normally be a candidate for an election
of councillor for an electoral division or ward in the local authority
of which she or he is the elected mayor. The exception being that
where the mayoral and councillor elections in that local authority
are taking place at the same time, in which case the elected mayor
may stand for election to either or both of the offices and if
elected to both offices a casual vacancy in the office of councillor
for the relevant division or ward arises.
