"But I have been horrified as, bit by bit, we have abandoned these commitments - domestically and on the world stage. The Kept Animals Bill has been ditched, despite your promises. Our efforts on a wide range of domestic environmental issues have simply ground to a standstill."
"More worrying, the UK has visibly stepped off the world stage and withdrawn our leadership on climate and nature."
"Indeed the only reason the government has not had to come clean on the broken promise is because the final year of expenditure falls after the next General Election and will therefore be the problem for the next government, not this one."
"I will never understand how, with all the knowledge we now have about our fundamental reliance on the natural world and the speed with which we are destroying it, anyone can be uninterested."
"Too often we are simply absent from key international fora. Only last week you seemingly chose to attend the party of a media
baron rather than attend a critically important environment summit in Paris that ordinarily the UK would have co-led."
"Worse still, we have effectively abandoned one of the most widely reported and solemn promises we have made on this issue; our pledge to spend £11.6bn of our Aid on climate and environment."
