When Zack Polanski took the reins of the Green Party of England and Wales last September, the party was a tidy operation of 68,000 members. It was comfortable, predictable, and fundamentally built for a minor political player. Fast forward to June 2026, and that membership has surged past 230,000.
Tripling your size in less than a year sounds like a dream. But behind closed doors, senior party officials are realizing it's closer to a logistical nightmare.
The Green Party is facing a full-blown identity crisis. The very structures that make them feel distinct from the major Westminster machines are now threatening to paralyze them. If you've been wondering why a party polling at 19% nationally isn't moving faster to capitalize on Labour's recent internal instability under Keir Starmer, look no further than how the Greens actually make decisions.
The Myth of Direct Democracy in a Mass Movement
For decades, the Greens have prided themselves on a pure, bottom-up model. Decisions aren't handed down by a shadowy committee or a single powerful leader. Instead, policy is decided through a direct-democracy framework. Members vote on the party platform at two annual conferences.
It looks great on a leaflet. In reality, it doesn't work when you have nearly a quarter of a million members.
Right now, policy is decided exclusively by the people who physically show up to conference. We aren't talking about hundreds of thousands of people voting. We're talking about roughly 1,000 people inside a conference hall making decisions for the entire movement.
Think about who can actually do that. You need the money to buy a train ticket, the disposable income to book a hotel room for several days, and a job that lets you take time off. It creates a self-selecting group.
Even worse, this hyper-local, in-person system leaves the door wide open for organized fringe activists. When a tiny, motivated faction can pack a room, they can hijack the policy book. Look no further than the spring conference in March, where a controversial grassroots motion attempted to formally commit the party to the stance that "Zionism is racism." Whether you agree with that position or not, having massive, geopolitically sensitive platform shifts decided by 0.05% of your total membership is a terrible way to run a serious political force.
Zack Polanski and the Leaderless Leadership Problem
If the Green Party wants to win more council seats and expand its parliamentary presence, it has to fix its management structure. Some senior party figures are quietly whispering that Polanski is too focused on being a broadcast spokesperson and not focused enough on fixing the machine.
But to be fair to Polanski, his hands are tied by design.
Until 2008, the Greens didn't even have leaders. They had "principal speakers." Even today, the leader is shockingly weak compared to the leaders of Labour or the Conservatives. Polanski holds just one vote among roughly two dozen members on the party's executive committee. He can't reshape policy on the fly. He can't pivot quickly when major national events unfold. He won 85% of the members' votes when he took over, giving him a massive personal mandate, yet he has almost no administrative power to act on it.
Some insiders want to give the leader more trust and leeway to make the party agile. Others are terrified of losing the grassroots soul of the movement. It's a classic activist dilemma.
The Two Routes Ahead for Green Policy
The status quo can't last. Senior Greens are currently debating two main options to change how they vote, and both come with major risks.
Option 1: The Delegate System
Local party branches would nominate specific delegates to travel, speak, and vote on behalf of their wider local membership. This is how traditional trade unions and older political parties operate.
- The Pro: It stops tiny, radical factions from dominating a room just because they live near the conference venue.
- The Con: It feels institutional. Grassroots members will inevitably feel like their direct voice is being taken away and replaced by party bureaucrats.
Option 2: Universal Online Voting
Keep the one-member, one-vote system but move the ballots online so all 230,000+ members can participate from home.
- The Pro: It's genuinely democratic and eliminates the financial barrier of attending physical conferences.
- The Con: It requires massive digital infrastructure and cash that the party simply hasn't had.
While the Greens' financial position is improving alongside their polling numbers, they are still desperately short on the administrative resources needed to handle a surge of this scale. They are trying to run a major national campaign with a back-office staff designed for a regional pressure group.
What Happens Next
The clock is ticking. With political seismic shifts happening on the left—especially as regional figures like Andy Burnham shake up the broader progressive landscape—the Greens cannot afford to spend the next two years arguing about their own rulebook.
If you're a Green Party member or a prospective voter, here is what needs to happen next to keep this momentum from stalling:
- Demand Digital Voting Options: Pressure local and national party executives to prioritize secure, remote voting infrastructure before the autumn conference cycle.
- Clarify Executive Powers: The executive committee needs to establish clear, temporary emergency powers that allow the leadership team to respond to fast-moving news cycles without waiting six months for a conference vote.
- Focus on Local Branch Funding: Instead of funnelling all new membership revenue into national broadcast campaigns, resources must go toward professionalizing local regional offices to manage the influx of new volunteers safely and effectively.
