<P> In the UK ( other than in Scotland ) a person must be aged 18 or over ( 16 in Scotland ) to stand in elections to all parliaments , assemblies , and councils at the European , UK , devolved , or local level . This age requirement also applies in elections to any individual elective public office ; the main example is that of an elected mayor , whether of London or a local authority . There are no higher age requirements for particular positions in public office . Candidates are required to be aged 18 on both the day of nomination and the day of the poll . This was reduced from 21 by the Electoral Administration Act 2006 . </P>
