Meet Cat Arnold 🌹 Sitting NEC rep, vice-chair for women, and the candidate who topped CLP nominations this year. A Labour Party that draws on the wisdom, energy and talents of its whole movement needs people like her at the table. Vote Cat Arnold in the CLP section.

🗳️🌹🗳️🌹Huge thanks to our friends at the Labour Campaign for Electoral Reform for recommending a vote for Cat Arnold, Jovan Owusu-Nepaul and Kerry Postlewhite - all members of LCER - in this year's elections to Labour's NEC! See our regional ranking recommendations below!

In this year's election, three candidates are members of LCER - Catherine Arnold serves on our Executive Committee, and  Jovan Owusu-Nepaul and Kerry Postlewhite also belong to LCER.

Please consider ranking these as your top three choices (and if you're a member of Mainstream, it will make sense for you to place them in the recommended order for your region). All three are endorsed by Ann Black, longstanding member of LCER and of the NEC.

We have seen over the last 2+ years what happens when the Labour Party listens only to select voices. We need an NEC that represents the broad church, guiding the Party as it resets itself. I’ve voted for these Mainstream candidates, plus trans ally Jess Barnard, with Abdi Duale for balance.

Decidly odd not to be voting for @annblack.bsky.social in this year's NEC election. Someone who helped me numerous times with issues and queries when I was a CLP chair. Its great to see her endorse our Mainstream NEC team. People I know will bring the same commitment to our members as Ann did!

For 25 years, @annblack.bsky.social has championed party members on Labour's NEC. We're thrilled that she's backing Cat Arnold, Kerry Postlewhite and Jovan Owusu-Nepaul this year. Support the Mainstream team to continue Ann's tireless commitment to transparency and democracy 👇

Cat Arnold was elected to the NEC in 2024 as part of a hastily assembled women’s mini-slate.  She is committed to accountability, and since joining the NEC she asks all the questions which I asked when elected back in 2000.  Given time she may even be able to track down some answers.  She has just been elected as the joint NEC vice-chair for women, and her statement is here.

Jovan Owusu-Nepaul worked for the party’s equalities team, and stood as the Labour candidate in Clacton in 2024.  Few people know more about campaigning against the Faragists, and after he visited Oxford I can recommend him highly as a speaker for party meetings.  His statement is here.

Kerry Postlewhite was also a parliamentary candidate in 2024, and can empathise with the experiences of candidates and members in non-priority seats.  She worked for the Socialist Group of MEPs, including Labour MEPs, for more than ten years.  Her statement is here.

I’ve tended to avoid voting by slate - I want to choose my candidates according to their beliefs and what they’re actually going to do for people. Today I’m supporting candidates who are Mainstream supporters because of the principles they’ve signed up to (see below):

On Andy Burnham’s Announcement as Leader of the Labour Party:
Mainstream’s Interim Council sends its congratulations to Andy Burnham on becoming Leader of the Labour Party and, from Monday, Prime Minister of the United Kingdom. 

We were proud to launch with his backing last year, and like the whole Labour movement, we are hopeful for this shared opportunity to write a transformative new chapter for the country. This is our final chance to defeat the forces of the authoritarian right, pull our party back from the brink and build a country that shifts power and wealth decisively back to the majority. To deliver on the promise of “change” we made in 2024, what comes next must be radically and meaningfully different. Business as usual must end.

We face a growing inequality and climate crisis, which is feeding spiralling living costs and a basic sense of scarcity, injustice and unfairness across the country. To tackle it, Labour must be prepared to invest in the bonds that hold communities together, pioneering a new political economy and rebuilding our broken democracy. In our recent paper, The Productive State: A Framework for Manchesterism, we set out in detail how this new settlement can take shape. 

Facing international instability, Labour must champion solidarity, human rights, and collective action. We must reject the extraction, exploitation and grotesque inequalities promoted by domestic and global economic systems.To win support for a popular, principled, and practical left politics, Labour must also change within. We must unlock the wisdom, talents, and energy of all of our members and our wider movement to lead the change our country so urgently needs. Our new leadership must root out the factionalism and insularity of recent years, embracing democracy, pluralism and participation.

This should start with the full implementation of the recommendations of the Forde Report on Labour Party culture. It also demands that our new leader’s first Cabinet properly represents our party’s tradition as a broad church, not a boys’ club. We hope, in particular, to see the appointment of a progressive Chancellor with vision, values and a record of delivering structural change; someone who understands the threat that climate breakdown poses to people and planet and who has the courage to rebuild our state’s productive capacity.

May’s devastating election results showed that, in every nation and region of the UK, vast swathes of voters have lost faith in Labour. Party membership has sunk to a dangerous low, and much of our movement feels dejected and disempowered. The process to change the leadership did little to address this at the grassroots. Labour have been given a lifeline - but we are by no means out of the woods. Change at the top is necessary, but to make hope a reality, this next chapter for Labour and the country must follow a genuinely different path. 

We look forward to playing our part in making real change happen - but we do so with our eyes wide open to the scale of the fight ahead.
