First-past-the-post builds a direct relationship between a community and their MP. Residents come together to decide who most people want as their national representative. No one has more than one vote and it has to be cast responsibly.

AV does not bring you greater proportionality - and there is a tendency for parties to gang up on one of the major ones to run an 'anyone but' campaign.

When one party is really unpopular, like the Conservatives in 1997, AV can really skew the result disproportionately against them.
