By its nature, the progressive disposition tends to dissatisfaction. We have dreams for a better world, we are angry at injustice, we have a significant belief in the power of government to change things, and we have an optimistic view of human nature. So should we be satisfied or dissatisfied with the last decade, and how should we renew the progressive agenda?

Progressive politics has shown a capacity for economic stewardship in a way it never has before in this country. Public investment has helped to regenerate our public services and create new institutions of the public realm, like Sure Start. Working people have seen gains in income and rights, from tax credits to paid holidays. The ethos of the country has shifted to the left on gay rights, the environment, development, and even taxation and spending.

What matters is whether these gains are the start, or the end. This period of progressive rule was never going to be 1945 to 1951: the big bang. The model for us is surely closer to Scandinavian social democracy: sustained incremental change which knits progressive values deep into the fabric of the country. Why does this matter? Because it shifts the centre ground of politics irreversibly onto progressive terrain. By that standard, there is all to play for.

As many have pointed out, renewal in office is one of the hardest things to achieve. But it is not impossible. It requires some key ingredients. First of all, ethos: shining through from every action and proposal should be a sense of what progressive politics is about. Second, clear priorities: how does progressive politics specifically answer the challenges of building a society with the ethos we want to see? Third, political practice: can we live our ethos through the way we conduct our politics?

The first building block for an ethos of progressive politics must be equality – including a belief that all should have a fair chance to achieve their potential. Part of being in progressive politics is a faith that people can achieve extraordinary things, but they need the right opportunities to do so.

In our pursuit of equality, three particular challenges face us far more starkly than they did in 1997: the challenges of the environment, of globalisation, and of asset-based inequality. In different ways, they make the traditional pursuit of equality more difficult, but they also make the case for progressive politics clearer than ever.

Achieving environmental sustainability requires that markets be embedded within the laws and norms of society, which reflect a set of social and political values. Globalisation shows that government must play its necessary role to ensure that people are not left isolated, and the benefits and burdens are fairly shared. Issues in the housing market call for looking at the potential for giving more of a priority to providing greater housing, in all its forms, and looking at ways of enabling individuals to build up assets.

But, with these greater pressures facing the egalitarian project, the most important area of policy remains education. And though school reform and investment need to continue, creating a more equal society cannot be done in the classroom alone. We know from the past decade that we also need a focus on what happens before children get to school, what happens out of school, and their career pathways after school. That means childcare, youth services and vocational skills must all be greater priorities in the years ahead.

Equality is one part of the progressive ethos. But there is more to the good society than the aggregation of the ‘I’: my health, my education, my job, my house, my pension – important as these things are. The challenge is also to address the wider question of not just what each achieves for themselves, but how we relate to each other and what kind of society we are.

The central idea here is that the good society we believe in is underpinned by us holding a set of values in common, around solidarity and concern for others. Public institutions and practices can help bring people together, build solidarity and connect groups that would not otherwise interact. Sometimes this may be about new institutions, such as better youth services or new public spaces offering cultural or community facilities. Also, it is about how we use and build on existing institutions – schools, health centres, libraries and other public places – and about how government supports third-sector institutions to help build stronger communities.

These two parts of our ethos, equality and community, lead us to a third: empowerment. Compared to 10 years ago, from the private economy to public services to our democracy, people are rightly demanding more control. The decline of deference, raised expectations, as well as the advent of the internet, give people a reason to believe that they can exercise a greater decision-making role in their own lives and that of their communities.

Empowerment is the partner of equality, not just because the distribution of power is one dimension of equality. Our whole notion of equality must be based on a belief about the individual as author of their own life. The distinction between the progressive and conservative story is that we believe individual empowerment is the partner of the enabling state, not an alternative.

Taking empowerment seriously means we need both to devolve more power to local government and to find ways of engaging individuals in decision-making which go beyond a once-every-four-years election. People’s disengagement from the political process must, in part, be explained by a belief that their involvement will not make a difference.

With a firm ethos of equality, community and empowerment, we need to think about how we put these into effect. We need to look at our political practice.

The attraction of the progressive project before 1997 was its sense of empathy: a notion that we, better than the alternative, understood the struggles and aspirations of ordinary families. After empathy comes analysis. We need a story about Britain and about people’s lives which points to the role of progressive politics. And we need candour, being honest about the challenges and dilemmas facing government and our society.

Above all, for a party 10 years in government, we need idealism. The momentum behind debt and development shows how we can build alliances which go beyond government and party to embrace a wider cause and community. We need to do the same on big domestic issues like child poverty, where we need to also tap into people’s willingness to be part of a big movement for change.
