Hung parliament: what the Lib Dems would demand

• Electoral reform. For the Liberal Democrats, this is the big issue and it will be the price for their support in a hung parliament. The party wants the single transferable vote (STV) system of multimember constituencies, in which voters rank candidates in order of preference, to be on the ballot paper in a referendum. Clegg acknowledges that neither Labour nor the Tories would agree to this. Labour is proposing the alternative vote system, in which voters rank candidates in order of preference in the existing 650 constituencies. The Lib Dems would demand the more proportional alternative vote plus system, proposed by the Jenkins commission in 1998. Jenkins said that of the then 659 MPs, 579 should be elected by pure AV. The rest on a "top up" system that would balance the vote nationally to ensure a more proportional result. • Making the tax system fairer by introducing a £700 tax cut for all but the richest earners by making the first £10,000 of earnings free of income tax. • Focusing educational resources on pupils from deprived backgrounds. • Making the economy less dependent on the City, boosting green industries.
