Politics at the moment for progressives feels a bit like being imprisoned in a sound-proofed chamber. We’re shouting loud. We’re gesticulating madly at the bogey man coming round the corner. But the voters can’t hear us. Worse, they actively don’t want to hear us.

So far, Labour’s approach has been to try and get its future offer to the electorate sorted. New ideas are the lifeblood of progressive politics – they inspire activists and give voters something concrete to hold us to. It’s good to see, therefore, that Labour’s leadership looks ready to put mutualism at the centre of the manifesto and that the cabinet finally embraced the idea of trying to get a referendum on the Alternative Vote into law before the general election. It is a shame that the drive towards greater constitutional reform has come so late in the day, but it will help to provide a crucial difference between Labour as the party in favour of changing the political status quo, and the Tories, whose first reform instinct is to cut the size of the Commons to make it easier for them to win elections.

The manifesto will obviously be crucial in proving how bold Labour intends to be in a fourth term, and with that in mind Progress has been putting forward a few ideas of our own. But ideas aren’t enough in themselves. What is needed is a broader narrative which provides coherence for those ideas and a sense of direction. Dare we say it, but what Labour needs is an ideology. James Purnell made the case for this most eloquently in a speech in February to the London School of Economics. He argued that New Labour’s lack of an ideology blighted its time in government for three reasons. First, because it made it hard to prioritise between competing interests and causes. Second, because without an ideology it’s more difficult to see inconsistencies in your approach. Purnell picked up on New Labour’s emphasis on choice in public services, but reluctance to increase choice in democracy, as examples. Finally, he argued that it is hard to build ‘an enduring coalition for change’ without an ‘ideological washing line’ upon which to hang policies.

It is this third point which is most interesting and which those involved in whatever replaces New Labour should focus their thinking on. New Labour took root in the decade when Francis Fukuyama famously declared the end of history and the end of the ideological clash between totalitarianism and liberal democracy. Fukuyama was rubbished then, and subsequent events including 9/11, the threat of climate change and the pressing challenge of global poverty, have proved him wrong still further. But the fall of the Berlin Wall provided a backdrop which made ideology look redundant in the uplifting 90s. The 1997 manifesto stated New Labour’s opposition to ideology clearly: ‘New Labour is a party of a party of ideas and ideals but not of outdated ideology. What counts is what works. The objectives are radical. The means will be modern.’ Eventually, New Labour had to respond to its lack of ideological underpinning with the development of the Third Way, but it wasn’t enough to provide the intellectual ballast to support a movement after the departure of Tony Blair.

So what might a new articulation of Labour ideology look like? Purnell’s answer focuses on the notion of power using Amartya Sen’s theory of capabilities as a starting point. There is an elegance to his argument that the task of the left is to make the individual more powerful – by attacking concentrations of economic power, by taking power away from the state and devolving it to people, and by creating an organised movement to empower people on the ground, in our communities. This isn’t new – Purnell cites R H Tawney extensively as a guide to rediscovering Labour’s zeal for putting power in the hands of people – but as the basis for the debate at the coming election, and beyond, it’s an exciting place to start. It leads Purnell to argue for a living wage, a cap on the cost of credit, state guarantees of work and opening up school catchment areas, as well as continuing more familiar New Labour policies such as placing conditions on benefits and extending control of public services through things such as individual budgets.

As Paul Richards argues in this month’s Progress magazine the first major collection to be published by Demos’s Open Left project, which Purnell heads up, Labour isn’t ‘intellectually bankrupt’, despite the media’s desire to paint the picture that way. It will be hard to win the election from the position Labour is in, but there is just about time left to use power as a theme for the campaign. It will take us head to head with the Conservatives who are edging towards this territory. But we know that audacity wins elections. Perhaps power is Labour’s way of breaking through the glass.
