Our reaction to the Prime Minister’s speech in @labourlist.bsky.social 🌹 Radical realism in action. Mainstream Labour values in practice.
'Radical realism in action'
Mainstream, a soft-left group backed by Burnham, said that the speech delivered on their calls for radical
change.
The group's interim council said: "Andy Burnham - our Prime Minister, the leader of the Labour Party, and a signatory to Mainstream's founding statement - just announced some of the most radical reforms this
country has seen for the best part of a century.
"Electoral reform. Public control. A new settlement for social care. And much, much more.
"Radical realism in action, Mainstream Labour values in practice. We're not just changing the Labour Party, we are changing the country."

Thank you to the hundreds of you who joined us Monday to celebrate Mainstream's first year. In just twelve months, we've helped shape the Labour Party taking form today. Now we’ll do what Ed suggested: support and pressure. That’s how we’ll transform the country.

Our friends at @serauk.bsky.social challenging the CAC’s decision to rule out our joint motion calling for public ownership of water. Privatised water has failed. We need public ownership now - and Labour must be able to debate bold ideas to achieve real change. #LabourConference2026

We’re deeply concerned that Conference has been denied the opportunity to debate public ownership of water. That faction-driven procedure can stifle debate on essential services should concern everyone who wants Labour to be a confident, outward-looking movement.
On the CAC’s Decision to Block our Motion on Water Ownership

We are profoundly concerned that the Conference Arrangements Committee (CAC) has denied the Labour movement gathering in Liverpool the opportunity to debate public ownership of water. It is a policy supported overwhelmingly by the public and globally the norm.

That such an important question about the future of an essential public service can be stifled by faction-driven procedure should concern everyone who wants Labour to be a confident, outward-looking political movement.

Our Prime Minister, Andy Burnham, put it well when Mainstream was launched last year: “We’ve got to get beyond this culture where everything’s a threat. If people are speaking out, it can actually be an opportunity to make changes.”That principle matters. Labour will need bold ideas and serious debate if our government is to deliver the scale of change the country needs. Conference should be a place where our movement can test those ideas, challenge established thinking and develop new answers together - not one where important debates are prevented from taking place.

If Labour is to build the movement and the programme capable of changing the country, the Party must rediscover its confidence in its members: their ideas, their experience, their willingness to challenge orthodoxies and their capacity to think big about what a Labour government can achieve.

🌹🗳️ Labour members have voted for a much more diverse, open and pluralistic NEC. We thank everyone who supported the Mainstream team in these elections! Kerry and Cat will honour the trust you have placed in them.
2026 NEC Election Results

Labour members have voted for a much more diverse, open and pluralistic NEC: one that isn’t dominated by any one faction or tradition.

We thank everyone who supported the Mainstream team in these elections. Kerry and Cat will honour the trust you have placed in them, and work to properly represent you and all Labour Party members. Our commiserations to Jovan, a trailblazing black socialist in the Labour Party, who would have been a brilliant representative on the NEC.

This is the beginning, not the end, of Mainstream’s work to transform the Labour Party so that we can transform the country. And this is a seismic win for an organisation founded less than one year ago. To have achieved this result is a testament to the determination of our members and allies at every level of the party - and a sign of the appetite for the new politics that Andy Burnham is leading. We will continue our work to build that.
