The upcoming launch of a new left-wing party by former Labour leader Jeremy Corbyn and MP Zarah Sultana has sparked debate about the future of progressive politics in the UK. While the initiative could be seen as a rival to the Labour Party, it need not necessarily divide the left-wing vote, provided there is strategic cooperation between the various progressive forces.
The new party, which is yet to be formally named, shares common ground with the Green Party in its rejection of austerity, commitment to democratic reform, and belief in economic and ecological justice. Despite differences in emphasis, tone and priorities, these two projects could potentially coexist and collaborate effectively.
To counter the worrying rise of right-wing populism, the left must overcome fragmentation and find ways to cooperate. A non-aggression pact between the new Corbyn-Sultana party and the Greens at the next general election, with each standing aside in constituencies where the other has a better chance of success, could be a pragmatic solution. Joint campaigning on core issues such as proportional representation, protest rights, wealth taxes and a Green New Deal could also amplify their impact.
Framing climate action as central to economic justice, rather than a separate concern, could provide a unifying narrative for both parties. This is not about merging or blurring identities, but rather about strategic and political maturity. If the left cannot cooperate when so much is at stake, it risks handing the initiative to those who thrive on division and fear.
While some Labour sources have been dismissive of the threat posed by the new party, it’s worth noting that in 2017, the Corbyn-led Labour Party achieved 2.5 million more votes (and a 6% higher vote share) than Keir Starmer did in 2024. Even in 2019, 500,000 more people voted for Corbyn’s party than Starmer’s. This suggests that the new initiative could tap into a significant well of support on the left.
As one reader points out, Corbyn’s primary interest has been “winning the argument” rather than just winning elections. However, the realpolitik of foreign policy, particularly in relation to figures like Vladimir Putin and Benjamin Netanyahu, remains a concern for some. Nevertheless, the new party’s domestic policy platform, which aligns with many Green Party priorities, could resonate with a broad swathe of the electorate.
Ultimately, the success of the Corbyn-Sultana project will depend on its ability to forge strategic alliances and present a coherent, compelling vision for the future. In a political landscape increasingly dominated by polarisation and populism, the left must find ways to unite and amplify its voice.
