The City is made up of 25 wards. They are survivors of the medieval government system that allowed a very local area to exist as a self-governing unit within the wider city. They can be described as electoral/political divisions; ceremonial, geographic and administrative entities; sub-divisions of the City. Each ward has an Alderman, who until the mid-1960s held office for life but since put themselves up for re-election at least every 6 years. Wards continue to have a Beadle, an ancient position which is now largely ceremonial whose main remaining function is the running of an annual Wardmote of electors, representatives and officials. At the Wardmote the ward's Alderman appoints at least one Deputy for the year ahead. Each ward also has a Ward Club, which is similar to a residents' association.
