The Staggers 3 December 2012 Labour must not turn its back on pluralism Tribal differences have obstructed progressive change in the past. They must not do so again. Sign UpGet the New Statesman\'s Morning Call email. Sign-up In one day last week we saw the UK Independence Party (UKIP) record its best ever by-election result, a Liberal Democrat Deputy Prime Minister speak against his own government to support Labour's leader (whose own party was chalking up solid by-election wins as Lib Dem support evaporated) while a panicky Tory vice chair called for a deal with UKIP. Let's be suspicious of instant punditry that tries to tell us 'what this all means'. But, at the very least, it's safe to conclude that politics is not going to return 'to normal' anytime soon. Normal, to my generation, meant an essentially two-party battle with those odd (Liberal) Lib Dems occasionally winning. A younger generation saw that disappear in Wales and Scotland years ago, and a three-party system became the norm in England. But that, too, is now crumbling. We may not know where the votes of the disaffected will go, but with each passing election, fewer and fewer are likely to return en masse to Labour, the Tories or the Lib Dems. While that much is commonplace, too few people have asked what this means for progressive politics and for the chances of achieving progressive change. Labour instinctively believes that, even if politics is more volatile, it can become the default choice for progressive voters. In the short-term, that may be true in parts of England where the Lib Dems attracted a part of the progressive vote. It no longer works in Scotland and Wales, though, and all the signs are that it's not a long-term bet for England either. Rather than Labour re-establishing itself as the sole party of choice for progressive voters, it's more likely that the progressive vote will be split as it has now been for decades. In these circumstances, the chances of progressive change will depend on a political system and a political culture that enables the progressive views of voters to be reflected in the government of the day. It requires a pluralist political culture, a willingness to cooperate with others in order to deliver values that are shared among the voters of different political parties. A one nation Britain not only needs a one nation Labour Party capable of garnering support from many different voters in many different parts of the country, but an open approach to politics that builds alliances for progressive change. The launch of Labour for Democracy on 4 December is an attempt to break down tribal sectarianism and promote a pluralist culture within the Labour movement. The focus is not on coalitions or cross-party deals, but on finding ways of delivering what progressive voters want. We've already shown that, in the main, past Lib Dem voters hold similar values to Labour's, and quite different to most Tory voters. It's also clear that, despite the failures of the coalition, the public still generally want politicians to work together when they can, rather than exaggerate their differences. This isn't the easiest time to make the pluralist case. The Lib Dems' governmental and electoral performance is hardly encouraging, and has revealed a culture at times as sectarian as anything Labour has to offer. Meanwhile, Labour is doing well, and, of course, every party activist will work as hard as they can for every Labour vote. It is tempting to see pluralism as a sign of weakness, a lack of confidence; even an unwanted attempt to give Nick Clegg a permanent and undeserved place in government. But we must be bigger than that. Tribal differences have obstructed progressive change in the past. Voter allegiances to the major parties are declining as fast as the icecaps are melting. There are even signs that the ‘progressive majority’ that split its vote in the 1980s is itself shrinking in the face of recession and insecurity. If we want to change Britain in a progressive direction, Labour must show it is willing to work with, not just lead, everyone who will support all or part of that change. › Can South Africa's ruling party overcome its reputation for corruption, nepotism and violence?
