Well I do worry about it. I think that a deal would be much, much better. I think if we left without a deal, we and the EU would put in place all sorts of arrangements to make sure that the impact was mitigated. But it’s certainly not my favourite option.

We’ve been talking about some of the things that we would need to do both constitutionally and in other respects in order to make sure that the ambitions that we have for the environment are met. I don’t think intrinsically a no deal Brexit with the right policies is harmful to the environment. I think we can do the right thing with our own legislation and the international commitments that we make, but it would certainly be the case that it would be disruptive initially and that would be a difficult period.

We in government are seeking to be prepared for every eventuality, but it’s certainly not something I would contemplate with a glad heart.
