I agree with what the Leader of the Opposition said about President Trump. It is time that he re-engaged with the Paris agenda, and dare I say that that would be a good subject for after-dinner conversation? The right hon. Gentleman mentioned leading by example, and he is right that this country must do that even though we play only a small part in the overall global emissions. Should he become Prime Minister, where does he think coal should sit in the balanced energy policy of the future?
