The Alternative Vote Top-up, or Alternative Vote Plus (AV+), is a voting system intended for use in elections to an assembly or legislature. Under AV+ most candidates are elected from single member constituencies under the Alternative Vote (AV) system while a small number of candidates are elected under the regional list system. AV+ is not a parallel voting system. Rather, as occurs under the Additional Member System (AMS), under AV+ seats filled from regional lists are so allocated as to off-set the disproportionality created by the single seat constituencies and to achieve a measure of proportional representation.
