The '''Alternative Vote Plus''' (AV+) or '''Alternative Vote Top-up''' 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]] system while a small number of candidates are elected under the [[party-list_proportional_representation|regional list system]]. AV+ is not a [[parallel|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]]. ▼

AV+ may be considered a variant of AMS. However, unlike most versions of AMS, AV+ is not designed to deliver a high level of proportional representation. Rather, under AV+ the number of candidates elected from regional lists is kept to a relatively small "top up" in order to grant an in-built electoral advantage to larger parties. AV+ also differs from most versions of AMS in that the constituency seats are elected by means of the Alternative Vote rather than the [[First past the post|Simple Plurality]] ('First past the post') system.▼

▲AV+ was invented by the [[1998]] [[Jenkins Commission]], which recommended it as a system for use in [[United Kingdom general elections]], but no action has yet been taken on that committee's recommendations. The Commission described the system as a "limited" form of AMS aimed at achieving a balance between the requirements of "broad proportionality" and "stable government".
