SIR - It was thumbs-up last week for MPs voting to regard man-made climate change as an 'environmental and climate emergency' affecting this country (though this is non-binding).

Yet, thumbs-down should be the response to a third runway at Heathrow airport being given the go-ahead as well as the government still determinedly continuing to support the policy of fracking for fossil fuels in England.

If the public is looking for clarity, real leadership and an example on this issue, what they're actually getting are confused, very mixed messages!
