Polanski challenges Your Party ahead of its first leadership vote

The Greens are now the main party challenging Reform, according to some polls. Their leader Zack Polanski has just shared an X post dragging Your Party, seemingly urging the new party’s supporters to jump ship ahead of its first collective leadership election in February.

Polanski — “Killer statistics”?

While calling on all progressives to join his party, Polanski has previously resisted media attempts to divide the left by stressing his openness to collaborating with other progressives, including those in Your Party. And his 7 January tweet didn’t actually say anything about Your Party. But the message was pretty clear.

The post he shared said:

Nationally, Your Party is all but dead.

Next to statistics about Polanski’s popularity, it said:

Its voters have moved to another party.

We need to take on this failing unpopular Labour Government.

And take the fight to Reform.

Join the Green Party.https://t.co/0qbagSwgNX https://t.co/qnG4faDOr4

There are a couple of key caveats to the statistics above, though.

1. They show Polanski’s net favourability ratings from November, after two months of a massive Green surge and amid hiccups in Your Party. The figures for Zarah Sultana and Jeremy Corbyn, meanwhile, were from July, around the time they announced the founding process of Your Party.
2. They look at net favourability. This is the overall score once you subtract unfavourable opinions from favourable ones.

On point two in particular, the New Statesman article the X image came from shows Corbyn actually still held more favourable opinions than Polanski. The ‘net favourability’ issue for the former Labour leader comes as a result of his significant baggage, arising from the brutal smears he received during his time in that high-profile position.

In other words, unfavourable opinions of Corbyn are far higher than for Polanski, whom most people knew nothing about until a few months ago. Polanski has already faced some establishment attacks in his short time as Green leader, but hasn’t yet faced the relentless, multi-year assault Corbyn did.

All of the left will need to take on Labour and fight Reform

Party politics and the failure to forge progressive alliances in our awful electoral system arguably played a big role in letting the Tories rule for so long. So we absolutely will need everyone on the left to pull together if we’re ever going to move forward. And we’ll need to leave the ‘only our party can win’ mentality in the past.

The vast majority (around two thirds) of the ‘Progressive Activists’ section of society voted for Labour under Jeremy Corbyn, for example.

Then, Keir Starmer lost lots of voters to the Greens, even before the election of Polanski or the founding of Your Party. And while Progressive Activists made up almost half of Green supporters by mid-2025, there has also been a big grassroots buzz around what Your Party could become if it genuinely manages to do politics differently.

There is hope in both the Greens and Your Party. There is space for both of them. And they absolutely will need to work together in some way, along with others on the left.

We’re not surprised that outlets like the New Statesman would try to rubbish Your Party before it’s even got off the ground, though. Because the outlet has an establishment bias. And the writer taking digs at Your Party was Ben Walker, a Labour councillor. So his ‘doom and gloom‘ approach to Your Party is hardly surprising.

Your Party, however, has members all around the country. And there are reasons they haven’t already joined the Greens. So if the left is to pull together to take on Labour and fight Reform, the spirit of collaboration Polanski, Sultana, and Corbyn have hinted at previously will need to continue.
