How much would AV referendum in UK cost?

John Redwood ruminates in his blog about the costs of the planned referendum about the introduction of the AV voting system in England. But Dirdem argues that AV alone will not change much. Also irrelevant to ask how much the AV campaign may cost, it is pittance in comparison to total budget. One has to ask what are the costs of a dysfunctional democracy where voters are reduced to box tickers at the discretion of the sitting government or once every five years. The remoteness of government (and it is not much better in most ‘Western’ Democracies) due to this pseudo-democracy can only be ended by a system of Direct Democracy
