Some systems also allow electors more choice when casting their vote. This means that, if their chosen candidate has no chance of winning and no candidate has the support of more than half the voters, their vote can be transferred to their second choice and so have more chance of counting. Because all votes count, there is much less need for tactical voting. However, AV is not a proportional system and would not provide a fairer distribution of seats. In constituencies with more than one MP, each party will put up more than one candidate.
Some systems allow voters to choose between the candidates of the same party.
They can then cast their vote on the basis of gender, age or views on issues such as Europe, as well as on the basis of party. This system also makes it more likely that more women and black and Asian MPs will be elected.
