AV will not increase the chances of smaller parties winning a seat. The 50 per cent threshold makes this less likely than with a simple majority system. Caroline Lucas, for example, was elected with 31 per cent of the vote in Brighton Pavilion. The reason smaller parties do not win more seats under FPTP is down to the scarcity of resources, the cost of campaigning and the geographical density of their smaller support. None of these are issues addressed by the introduction of AV.
