FPTP must go, but we must be careful what we replace it with: the list system is absolutely disastrous, more or less guaranteeing any party that puts up candidates at least one MP, so extreme, unrepresentative parties end up holding the balance of power. It also means that no-one has an MP of their own. Israel uses it, with disastrous results. Additional member is a crude cobbling together of fptp, which we want to get rid of, and the list, which is, as i say, even worse than fptp. What we need is single transferable vote.
