Natalie Bennett, Green Party Leader, said:
"The selection of Corbyn, combined with the remarkable Green surge of the past year , and the SNP's successes in the Westminster election, shows just how many people support an alternative to austerity economics, a head-in-the-sand approach to our environmental crisis and our tired, business-as-usual politics.
"The Green Party shares Corbyn’s opposition to austerity, Trident nuclear weapons, and the sell-off of public assets and will be delighted to work with his Labour Party and others who share our views on these and other issues.
"The Green Party is committed to standing up for migrants and refugees and calls on the new Labour leader to challenge the government’s feeble and inadequate response to the global refugee crisis.
"In addition, we hope to engage Corbyn and the Labour Party in discussions about the urgent need for electoral reform. As the May 2015 General Election proved, our outdated and unrepresentative system fails both democracy and the electorate.
"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."
"The Green Party’s doors continue to remain open to those who want to create a new kind of progressive politics, working, as we have been consistently for decades, for a society in which no one fears not being able to put food on the table or keep a roof over their head, while we all collectively live within the environmental limits of our fragile planet."
