When Jeremy Corbyn and Zarah Sultana unveiled their new political project in March 2026, the response was swift and staggering: more than 700,000 people signed up within a week, with 80,000 joining in just the first five hours. Your Party, as they named it, arrived as a socialist formation built around wealth redistribution, nationalisation, and fierce opposition to NHS privatisation. Eight months on, the party has registered with the Electoral Commission, elected its first officers, and found itself navigating internal fractures that threaten its early momentum.

What is the Jeremy Corbyn new party website?

The official online home for Your Party is yourparty.uk, where visitors can find the party’s founding mission statement and details on how to get involved. The site positions the party as a vehicle for building a “fairer society” through wealth redistribution, nationalisation of key industries, and investment in social housing.

On the homepage, Corbyn and Sultana’s joint statement outlined the core policy ambitions: breaking up concentrated wealth, re-nationalising the railways and energy sector, and opposing any further privatisation of the National Health Service. The site also serves as a portal for branch formation, with the party emphasising that local groups would have meaningful autonomy to stand candidates and communicate directly with members.

Beyond the official party platform, Jeremy Corbyn maintains jeremycorbyn.org.uk as his personal presence, though this functions separately from Your Party’s communications.

Official site details

The yourparty.uk domain was active from the party’s launch in July 2025, and serves as the primary digital interface for members and potential supporters. The site includes sign-up functionality, which proved critical in the party’s explosive early growth.

Homepage mission statement

Your Party’s stated mission centres on creating a “truly member-led” socialist party. Their founding documents emphasise opposition to austerity, support for Palestinian rights, and a commitment to environmental transition “done fairly.” The party operates under a collective leadership model managed by its Central Executive Committee.

Bottom line: Your Party’s website is yourparty.uk — the hub for membership, policy updates, and branch organiser resources. The mission is unabashedly socialist, but the internal fractures visible at the April conference raise questions about whether the “member-led” promise can survive factional conflict.

What are the membership numbers for Jeremy Corbyn’s new party?

The headline figure from Your Party’s launch period remains striking: over 700,000 people signed up to support the initiative within its first week. More than 80,000 joined in just the first five hours after the announcement. These numbers were reported across multiple sources, including the Socialist Party UK and Wikipedia citing party announcements.

What the available evidence does not provide is a current, precise membership count. At a hustings event, party representatives indicated approximately 60,000 members at that point. No verified update to that figure appears in the sources reviewed. The party has not published quarterly membership disclosures comparable to what larger parties release, making precise tracking difficult.

What remains unknown

The gap between the 700,000 initial sign-ups and the 60,000 figure cited at hustings raises questions about conversion rates — how many mailing list subscribers became paying members versus casual supporters who simply registered their interest.

Current figures

Based on hustings footage, Your Party had roughly 60,000 members as of the event date. This represents a significant drop from the initial surge, though without a timeline for when that 60,000 figure was recorded, its currency is uncertain. The party has not released audited membership figures as of April 2026.

Growth trends

The pattern emerging from available data suggests dramatic early interest followed by a stabilisation around a smaller active base. Whether membership has grown, contracted, or plateued since the hustings event cannot be confirmed from current sources. For comparison, the Liberal Democrats — the UK’s third-largest party — report roughly 100,000 members, while the Greens hover around 50,000.

The upshot

If Your Party’s 60,000 estimate holds, the party is already comparable in membership to the Green Party of England and Wales. Whether that figure is current or has since shifted will depend on whether the party opts to publish membership data going forward.

What is the name of Jeremy Corbyn’s new party?

The party is called Your Party — stylised as “Your Party (UK)” in some formal contexts to distinguish it from any future international counterparts. The name was chosen deliberately to emphasise the party’s stated commitment to member-led governance, positioning supporters not as passive backers but as owners of the project.

Zarah Sultana announced on 3 March 2026 that she was leaving the Labour Party to co-found this new political formation alongside Jeremy Corbyn. The Electoral Commission officially registered Your Party on 30 March 2026, with Jeremy Corbyn listed as the registered leader at that time.

Official name

“Your Party” serves as both the public brand and the legal entity name. Registration with the Electoral Commission under this name grants the party official status for contesting UK elections. The Commission’s requirements mean that while the party operates under a collective leadership model internally, the official registration lists a single named leader.

Background

The formation represents a direct break from Labour after years of friction. Corbyn led Labour from 2015 to 2020, but was succeeded by Keir Starmer and effectively expelled from the party in 2020 over his response to antisemitism allegations. Sultana, MP for Coventry South, remained a Labour MP until July 2025, when she announced she would not seek re-election under the party banner.

Bottom line: Your Party is the name — simple, direct, and deliberately democratic-sounding. But the name alone cannot resolve the tension between the party’s “member-led” rhetoric and the Electoral Commission’s requirement for a single named leader, a discrepancy already visible in the leadership transition from Corbyn to the collective CEC model.

What is the polling for Jeremy Corbyn’s new party?

Public polling data for Your Party remains limited. The party is in an early electoral phase, and major polling firms have not yet included it in regular tracking. This is not unusual for parties that have just completed their founding conference and are preparing to field candidates in upcoming local elections.

The May 2026 local elections represent a first real electoral test. How Your Party performs in those contests — whether candidates win seats, draw meaningful vote shares, or fail to clear the threshold in many wards — will provide more concrete data than any pre-election poll.

Polling context

For new parties in the UK, the polling window often opens only after a first electoral showing. Reform UK, for instance, gained measurable polling support only after winning its first parliamentary seats. Your Party’s trajectory will likely follow a similar pattern.

Recent polls

No verified polling data specifically measuring Your Party support appears in the sources reviewed. National tracker polls from YouGov, Survation, and other firms have not listed Your Party as a prompt option. Until the party contests elections and shows vote totals, polling firms have no data to report.

Performance indicators

The most concrete performance indicator available is the CEC election outcome from February 2026, where the Corbyn-aligned “The Many” slate won 14 of 24 seats against Sultana’s “Grassroots Left” with 7 seats and 3 independents. This internal result suggests strong Corbyn-supporting majorities within the active membership, but does not translate directly to electoral support.

Bottom line: Polling data is sparse because Your Party hasn’t yet stood candidates in major elections. The May 2026 local elections will provide the first real electoral readout — and that data will matter far more than any pre-election poll for a party still building its branch infrastructure.

What is the latest news on Jeremy Corbyn’s new party?

The most recent significant development is the party’s first national conference in April 2026, which descended into internal conflict. Zarah Sultana, the party’s co-founder and MP for Coventry South, boycotted the event and publicly accused party leadership of fostering a “toxic culture” and conducting a “witchhunt” against dissenting members. Video from the conference was published online, showing Corbyn addressing delegates while Sultana’s faction refused to participate.

On 8 March 2026, the CEC had elected the party’s Officers’ Group, naming Jennifer Forbes as chair and Laura Smith — a former Labour MP — as vice-chair. Both belong to the “The Many” slate aligned with Corbyn, which had won a majority of 14 out of 24 CEC seats in the February election.

CEC election results

The CEC election outcome was the party’s first major internal democratic exercise and produced a clear majority for the Corbyn-aligned faction. “The Many” won 14 seats, “Grassroots Left” won 7, and independent candidates won 3. This gave the Corbyn faction a working majority on the committee that sets party policy and manages operations.

Leadership updates

Jeremy Corbyn formally became parliamentary leader of Your Party in March 2026, having been listed as the registered leader with the Electoral Commission since March 2026. The March 2026 appointment formalised his role ahead of the party’s first electoral tests. At the same time, the party registered changes to its nominating officer — Andrew Jordan replaced Adnan Hussain in December 2025.

Bottom line: Your Party’s September 2025 conference chaos exposes a fracture running through the project’s centre. Sultana’s boycott and accusations of a “toxic culture” suggest the “member-led” promise is already under strain less than a year after launch. For supporters considering involvement, the question is whether the party can resolve these tensions before the May 2026 elections — or whether they become the defining story.

What we know — and what we don’t

Confirmed facts

  • Your Party was announced in September 2025 and registered with the Electoral Commission on 30 March 2026
  • More than 700,000 people signed up within a week of the announcement
  • The party is led by a Central Executive Committee under collective leadership, with Jeremy Corbyn as parliamentary leader
  • Corbyn-aligned candidates won 14 of 24 CEC seats in February 2026
  • Your Party Scotland held its founding conference in February 2026, voting to support Scottish independence
  • First national conference in February 2026 saw Sultana boycott and publicly criticise party leadership

What’s unclear

  • Current precise membership total — the most recent confirmed figure is approximately 60,000 at a hustings event
  • Whether any published polling data exists for the party’s electoral support
  • How the factional conflict between The Many and Grassroots Left will resolve ahead of September 2025 elections
  • What specific policy positions the party will take into the upcoming local elections beyond founding principles
  • Whether Sultana will remain an active Your Party MP or distance herself further from the organisation

Your Party leadership and factions

Two distinct factions have emerged within Your Party, reflecting different visions for the party’s direction. The larger, “The Many” slate — aligned with Jeremy Corbyn — won control of the CEC with 14 of 24 seats. The smaller “Grassroots Left” faction, led by Sultana, holds 7 seats and represents a more hardline socialist position, particularly on issues of anti-imperialism and branch autonomy.

“I’m Zarah Sultana, your party MP for Coventry South and I’m standing with a grassroots left slate because we need a socialist anti-imperialist anti-zionist party that’s truly member-led.”

— Zarah Sultana, Your Party MP for Coventry South and co-founder (Your Party hustings video)

Sultana’s public positions at the hustings made clear the fault lines. She has called for branches to have explicit recognition, the ability to stand candidates in local elections, and access to membership data — demands that party leadership may view as already fulfilled or, alternatively, as challenges to central authority.

“That means our branches are recognized and empowered and are able to stand candidates in the May elections. It means membership data handed over to branches so they can actually communicate with their members.”

— Zarah Sultana, calling for expanded branch rights (Your Party hustings video)

The Electoral Commission’s requirement for a single named leader — which it does not recognise as shared or co-leadership — has created a structural tension that the party’s collective leadership model has not fully resolved. Corbyn was the registered leader at launch, but the March 2026 appointment of a parliamentary leader alongside the CEC’s Officer Group suggests an evolving hierarchy.

The paradox

Your Party launched on the promise of collective, member-led governance — yet the Electoral Commission, electoral law, and now internal factional disputes all point back to the need for identifiable leadership structures. Sultana’s boycott may force a reckoning on whether the party’s founding principles can coexist with the realities of running a registered political party.

What happens next for Your Party

The September 2025 local elections represent the party’s first major electoral test. How many candidates Your Party fields, in which wards, and with what level of local infrastructure will shape early coverage of the party’s electoral prospects. A strong showing would build momentum heading into any future general election; a poor result could deepen internal tensions.

Your Party Scotland’s trajectory offers a template — or a warning. Scottish members voted at their February 2026 founding conference to support Scottish independence and to move toward becoming an independent sister party. This suggests a federal model where regional branches operate with significant autonomy, which could either strengthen the party geographically or create further coordination challenges.

The unresolved factional conflict between The Many and Grassroots Left will likely dominate the coming months. If Sultana’s boycott signals a permanent split, the party loses its co-founder and one of its two sitting MPs. If tensions are papered over before May, the elections may provide a clearer picture of whether the party can present a unified electoral offer.

Why this matters

Your Party enters the 2026 electoral cycle as the most prominent left-wing split from Labour since the Social Democratic Party in 1981. Whether it grows into a lasting electoral force or fragments under the weight of internal disagreements will depend on outcomes in May and the durability of the Corbyn-Sultana compromise — if one can be found.
