The upcoming launch of a new party by Jeremy Corbyn and Zarah Sultana (Jeremy Corbyn and Zarah Sultana agree to launch leftwing party, 24 July) will inevitably prompt questions about whether this will divide the progressive vote or offer a genuine alternative to Labour’s centrist drift, especially as the Green party continues to grow as a principled voice for environmental and social justice. Although these projects are potential rivals, they need not be.
If the disturbing rise of rightwing populism is to be successfully confronted, the left must overcome fragmentation and find ways to coexist and collaborate. The Corbyn-Sultana initiative and the Greens share much common ground: a rejection of austerity, commitment to democratic reform and a belief in economic and ecological justice. Their differences in emphasis, tone and priorities are real but not irreconcilable.
