The hon. Lady mentioned the impact of Brexit. I am not trying to rehash the Brexit debate here, although we probably would have been on the same side. The Paris climate accord obviously includes countries outside the EU. We can show leadership and try to bring countries together from both inside and outside the EU once we leave.
Secondly, does the hon. Lady agree that a number of Members in this House are nationalists who want not only to break out of the EU but break up our own United Kingdom? Surely breaking up the component parts of the United Kingdom would not help us to tackle climate change in any way.
