The Greens have decided to enliven things by calling for a purge of heretics from within the government machine:

The Green Party of England and Wales has called for a purge of government advisors and ministers who do not share its views on climate change.

Any senior advisor refusing to accept "the scientific consensus on climate change" should be sacked, it said.

Party leader Natalie Bennett said the rule must apply to all senior advisors, including those with no responsibility for environmental issues.
