For this reason, even the Lib-Dems have, until very recently, avoided support for AV, given that it does not provide ‘proportionality’ between votes cast and the number of seats gained by each party. As with First Past the Post (FPTP), AV is a majoritarian system which elects governments on the basis of seats rather than votes. The system was rejected by the Jenkins Commission on electoral reform in 1998 on the basis that it not only fails to deliver any type of proportionality but, in some cases, it is likely to deliver even less proportionality than the current system. Thus, supporters of the ‘Yes’ campaign are certainly right to reject claims that the system would lead to regular coalition government. Studies of the effect of AV on past UK general elections have demonstrated that its impact on most electoral outcomes would have been minimal, delivering in most cases the same governing party, albeit with a slightly reduced majority, as FPTP.
