UK 1 July 2010 Electoral reform referendum “to be announced next week as set for May 2011” Left Foot Forward’s story will pile more pressure on David Cameron to reconsider his stance. Sign UpGet the New Statesman's Morning Call email. Sign-up Following my report that David Cameron is "considering" backing a "Yes" vote in a referendum on the Alternative Vote (AV) in order to seal the deal with the Liberal Democrats, Left Foot Forward has just broken the story that the referendum will be announced next week, and held next May. This further suggests that, in the wake of their providing crucial cover for Tuesday's Budget, the Liberal Democrats are reasserting their influence on the coalition. And it adds more pressure on Cameron to make it clear to Lib Dems, both in parliament and in the country at large, whether or not he is serious about sharing power. For if Nick Clegg fails to win any real change to Britain's warped electoral system, the Lib Dem participation in this Tory-led government will itself surely be deemed a failure. › Coalition economics: the view from the East End James Macintyre is political correspondent for the New Statesman.
