Alternative Vote Plus

The Alternative Vote Plus (AV+), or Alternative Vote Top-up, is a semi-proportional voting system. AV+ was devised by the 1998 Jenkins Commission which first proposed the idea as a system that could be used for elections to the Parliament of the United Kingdom.

As the name suggests, AV+ is an Additional Member System which works in two parts: the 'AV' part and the 'plus' part. As in the alternative vote system, candidates are ranked numerically in order of preference. The important difference is that an additional group of members would be elected through regional party lists to ensure a degree of proportionality; in typical proposals, these members are 15–20% of the whole body. More specifically, each voter would get a second vote to elect a county or regional-level representative from a list of candidates of more than one person per party. The number of votes cast in this vote would decide how many representatives from that county or region would go on to parliament.

Then Prime Minister Tony Blair issued a statement, saying that the report "makes a well-argued and powerful case for the system it recommends" and that "it is very much a modification of the existing Westminster system, rather than any full blown PR system as practised in other countries." He also praised Lord Jenkins for his work and gave the recommendations a cautious welcome, pointing out in particular that change would help address the "complete absence of Conservative representation in Scotland", a reference to the then most recent election in which the Conservatives failed to win a single seat in Scotland, despite winning 17.5% of the Scottish vote.

However, leading figures in the Cabinet at the time (e.g. Home Secretary Jack Straw, Deputy Prime Minister John Prescott, Chancellor Gordon Brown and Margaret Beckett) and the Labour NEC, all strongly opposed reform of the voting system, and blocked the chance of change at that time.
