In order to abolish an existing parish council, the principal council must provide evidence that this in response to "justified, clear and sustained local support" from the area's inhabitants. Where a new parish is formed with 1,000 electors or more, a parish council must be formed. Where there are between 151 and 999 electors the principal council may recommend the establishment of either a parish council or parish meeting. Where there are 150 electors or fewer a parish council may not be formed.
