In England and Wales, the position of returning officer in borough constituencies is held "ex officio" by the mayor or chairman of the borough or district council, and the high sheriff of the county in county constituencies. The administration of elections is carried out by the acting returning officer, who will typically be a local council's chief executive or Head of Legal Services. The role, however, is separate from these posts, and can be held by any person appointed by the council. The spending limits for election campaigns are different in the two, the reasoning being that candidates in county constituencies tend to need to travel farther.
