The launch

The Greens chose central London to launch their 2017 manifesto, with co-leaders Jonathan Bartley and Caroline Lucas sharing the stage to promise a universal basic income, a four-day working week and a final say for the public on Brexit.

Mr Bartley said his party's "Green Guarantee" contained "big and bold ideas which are possible", saying the Greens were "committed to redistributing wealth and power", reflecting Britain's place as the fifth largest economy in the world.

Personal pitch

Caroline Lucas, the party's only MP, said: "The Green Guarantee is about hope and we need hope now like never before.

"I can't remember a time in my own lifetime where the future has felt more uncertain - with Brexit, with accelerating climate change, with an NHS in crisis. We face challenges that we can't possibly pretend to fix in the next 100 days, or the next 1,000. Threats to our economic future, threats to our security, threats to our planet.

"But ours is a message of hope because we believe if we stand together for what matters, we can change the course of history."
