WHAT kind of discussion went through Downing Street and its think tanks before Theresa May told her ministers that, once again, blue is the new green and Tories are about saving the planet?

Was there no-holds-barred debate or did May, or someone who does her thinking, suddenly hatch a brainwave to take the initiative away from Labour and the NHS, offering an argument why it wouldn’t cost the Tories or their corporate backers anything?

“Look, it worked for Cameron. No longer the nasty party, hug a hoodie, hug a husky, pose as action man at the North Pole. Talk about clean energy, recycling etc. The kids’ll love it,” she or the thinker might have said.
