CLIMATE change became a point of contention inside the Green Party yesterday as members argued at this year’s conference on whether to prioritise the issue.

The Greens’ only MP Caroline Lucas set global warming front and centre in her address to conference, saying that protecting her sons from climate change was what got her “out of bed in the morning.”

But a heated debate erupted after her speech over whether combatting climate change should be the party’s flagship policy or just part of its principles.
