My right hon. Friend has said something that I regard as significant. Yes, we are going to try to achieve a multilateral approach at COP26, but if we do not succeed, we will consider a more unilateral approach. I am bound to say at this particular juncture, when the term “level playing field” is so commonly spoken about in respect of a certain negotiation, that it would surely be a distortion of international competition for some countries to be doing their best to deal with climate change and for other countries to be exploiting those efforts. If that is not a distortion of genuine free trade, I do not know what is. I think that the unilateral approach is justified.
