The Green Party offers congratulations to Jeremy Corbyn following his leadership win

"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 As the May 2015 General Election proved, our outdated and unrepresentative system fails both democracy and the electorate.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."

“Jeremy’s success in this contest is a real boost for progressive politics. For the first time in my memory Labour will be led by someone who stands up for the radical changes demanded by the challenges we face.

"I am looking forward to working with Jeremy to provide a concerted and strong opposition to this Government and to push for the constitutional changes, like reform of our voting system, that Britain’s multi-party, devolved political system demands.

"I will also be urging him to join me in championing urgent action on climate change and building an economy that works for our children and grandchildren - two of the greatest challenges we face."
