Other – Sept. 1, 2025

Mainstream is the home for Labour’s radical realists - those who know that to win again in 2029 we must offer the country not just a programme, but a vision of hope: a popular, principled and practical left politics for meaningful change.

Radical realism is the belief that big change is possible - and the commitment to make it both practical and popular. It means setting out how citizens, the state, civil society, and our Party can work hand in hand to transform our society for the better.

It means putting equity and justice at the heart of everything Labour does. It means rejecting an economy based on inequality and environmental destruction, and instead building one that shares the resources our society needs.

It means fighting for public services that meet these needs, inspire pride in collective provision and are built on long-term investment and the wisdom of the workers and users who sustain them. It means standing for the human rights and dignity of every person, defending liberty, protest and social protection at home and abroad, along with strong defences tied to democracy and the rule of international law.

It means recognising that our broken democracy must be remade through pluralism and dispersing power as widely and deeply as possible. It means forging cross-class alliances in every corner of our country and working with social movements for a democratic socialist future. And it understands that authoritarian populism can only be defeated by creating a national community that truly belongs to all of its people, and delivers for all of its people.

And finally, it means starting with Labour itself – unlocking the wisdom, talents and energy of all our members and supporters to lead the change our country so urgently needs.

Mainstream is the home for a popular left with heart and vision - radical in purpose, realistic in method, united in spirit. By galvanising the mainstream of our Party, we can win and we can transform Britain.
