I think—[Interruption.] The irony of that, given the debate within Plaid Cymru on nuclear, is not lost on me. But, let me say, what I would be saying to the classroom is that these things are not black and white, that you have to pick your moments and fight your battles. I'll take no lectures from Plaid Cymru on the record on climate change. I led the campaign to create an active travel Act. I set up the project in the IWA that is now doing ground-breaking work on setting out a map for renewable energy. Working across parties, I have been a key advocate here for the last two and a half years on the black route. So, I'll take no lectures from anybody on that side about sticking to principles. But there's a moment in politics when you strike and when you act. Now is not that moment. Now is the moment for others to pick each other's eyes out and score points, and I despair of it.
