The political party supporters who love Jeremy Corbyn more than Labour

In the Labour leadership election around 70,000 people who voted did not vote for the party in May's general election, and 40,000 of those voted Green, YouGov estimates.

In addition, 92 per cent of the previously Green voters backed Corbyn, showing his current dominance over the left wing of British politics.

The Green leader, Natalie Bennett, tweeted that Corbyn’s election was “the start of the end of Thatcherite Britain”, and said in a statement:

The selection of Jeremy Corbyn, combined with the remarkable Green surge of the past year, and the SNP's success at the General Election, shows how many people support an alternative to austerity economics, to the head-in-the-sand approach to our environmental crisis and to tired, business-as-usual politics.

We hope Corbyn will encourage his supporters to join with us and other campaigners working on these issues, and, in particular, on pushing the issue of climate change to the top of the political agenda ahead of the upcoming Paris talks.

On Tuesday, Jeremy Corbyn said that 30,000 people had joined the Labour party since his election as leader.

However, Bennett denies that the rise of Corbyn will siphon votes from the Greens, as she told the Huffington Post:

No, I don’t think so. What it will actually do is help to make more people take a look at us because our arguments are being put on a much broader field.

Meanwhile, writing in The Independent Caroline Lucas has invited Corbyn to forge an alliance of sorts against the Tories in 2020:

In the short term, for the next general election... my personal view is that there is potential in considering local grassroots electoral pacts where progressive candidates are standing, so as to give us the best chance of beating the Tories in 2020.

It's hard to imagine how a Labour/Green coalition of sorts wouldn't descend to in-fighting, given the tug of war the Labour party has between its own left and right. It's also hard to see how the left will unify at the next election.

One thing is certain: The Greens love the direction Labour is going.
