The Greens launched their election campaign on Thursday, hoping to build on their success in local and European elections.

Keith Taylor, the party's principal speaker, pledged to focus on climate change, the need for peace and protecting public services.

The Greens will field 200 candidates in the election.

"We are fighting on a platform of social, environmental and economic justice. And we unashamedly put peace, the planet and people at the very heart of our agenda," Taylor said.
