Union chief urges Angela Rayner to replace Starmer

A senior trade union figure has called for Angela Rayner to replace Keir Starmer as Labour leader, in a fresh sign of unease on parts of the party’s left as it braces for a difficult electoral year.

Maryam Eslamdoust, the general secretary of the Transport Salaried Staffs’ Association (TSSA), said it was “time Labour had a woman leader” as she questioned the direction of the government and warned about the threat posed by Reform UK.

Her intervention is striking not only because it comes from a prominent union leader, but because it names a specific successor. While calls for a leader to step aside are not unheard of in Westminster, explicit suggestions about who should replace them tend to raise the political temperature – particularly when the person being floated is the deputy prime minister.

A direct call for Rayner to take over

In comments reported by LBC, Eslamdoust argued Labour should look again at its leadership and suggested Rayner is well placed to lead the party.

“The Tories have had three women Prime Ministers and four leaders and we’ve had none. I think Angela Rayner is a credible figure,” she said.

Eslamdoust also challenged Labour figures who, in her view, talk about the need for more women in senior roles without following through. “I think some women MPs are making a lot of noise around there needs to be a woman deputy, but if they’re serious about that, they need to put their money where their mouth is and support Angela Rayner,” she added.

The TSSA chief’s remarks land at a tense moment for Labour’s wider coalition, with unions, members and MPs all watching closely for signs the government’s economic and public service plans are delivering improvements people can actually feel.

Downing Street pushes back: “No vacancy”

A spokesperson for Rayner was quick to play down any suggestion she is positioning for a contest with Starmer. According to LBC’s report, the spokesperson said: “There is no contest and no vacancy. Angela has been clear Labour must come together, avoid distraction and work as a team to deliver for the public.”

Downing Street also rejected the idea that the prime minister’s position is under threat, with a spokesperson saying Starmer has a “clear five-year mandate” and intends to focus on governing.

That public message – unity, discipline, no distractions – is familiar. But it also reflects the reality that leadership chatter has a habit of feeding on itself, especially when it is amplified by major public events, political setbacks, or an ugly news cycle.

Why unions matter so much to Labour

Trade unions are not just another stakeholder for Labour. They have historic links to the party, influence internal debates, and in some cases provide significant financial support via political funds. When senior union voices move from criticism to calling for a change at the top, Labour figures take note – even if the leadership’s immediate response is to dismiss it as noise.

It also matters because unions speak to Labour’s identity. A central tension in modern Labour politics is balancing the party’s traditional, movement-based roots with the pressure of governing in an era of tight public finances and fragmented voter loyalties. That tension is visible whenever union leaders argue the party needs to go further and faster on workers’ rights, wages, or public ownership.

In Eslamdoust’s case, she also urged Labour to move left, backing stronger protections for workers and arguing for nationalisations across rail, water and energy.

The Reform factor and the fear of a bad year

The union leader’s comments were framed around concerns about Labour being squeezed politically, including by Reform UK.

Reform’s rise has created a particular kind of pressure on Labour because it can pull at multiple fault lines at once: cultural issues, trust in institutions, anger about living costs, and a broader sense that politics is not delivering. Even where Reform is not winning seats, its presence can change campaigns, shape media narratives and force opponents to adapt.

That is why Labour strategists are likely to treat high-profile criticism as more than just internal grumbling. With important elections on the horizon, Labour will be anxious to avoid a story of drift or division taking hold – and leadership speculation is one of the fastest ways for that to happen.

What Rayner represents inside Labour

Rayner is an unusual figure in Labour’s modern leadership politics because she bridges groups that do not always agree. She has credibility with parts of the party’s left and the union movement, while also serving in the most senior ranks of a government led by a leader associated with Labour’s more centrist, managerial wing.

For supporters, that makes her a unifying prospect: someone who can speak authentically about working-class life and workers’ rights while also operating at the centre of government. For critics, her prominence is also a reminder that Labour has factions with very different instincts about what the party is and what it should prioritise.

Eslamdoust’s call is, in one sense, a personal endorsement of Rayner. In another, it is a political signal about what some Labour allies want the party to look like: more radical economically, more rooted in the trade union movement, and more combative in confronting a populist right.

Labour’s immediate calculation: close ranks

For now, Rayner’s team and Downing Street are clearly trying to shut the story down, stressing there is “no contest and no vacancy” and urging the party to focus on delivery.

That approach is not simply about protecting Starmer. It is also about preventing a feedback loop where every criticism becomes part of a larger leadership narrative, which then distracts from policy announcements and day-to-day governing.

But the underlying issues that produce these moments do not disappear because a spokesperson says they have. If Labour’s own allies are worried about the party’s electoral direction – and are prepared to say so publicly – then the leadership will need more than message discipline to steady the ship. It will need evidence, felt in households and workplaces, that the government’s plans are working.

For the moment, Eslamdoust’s intervention may not trigger anything formal. But it adds to the political pressure building around Labour’s performance, its relationship with the trade union movement, and the growing argument – voiced more openly now – about whether the party is being led in the right direction.
