It is absolutely true that we should not be getting into the Brexit debate, but I believe in co-operation at every level, and the environment that has been created in this House in the past two years against the European Union is very damaging to international co-operation.
Our closest geographical neighbour is the European Union, and we should work very closely with it. That is why the best thing we can do if we are serious about climate action is to stop Brexit. History will not look kindly on us for leaving the European Union just at the moment when our moral responsibility is to protect our planet and work together. We should be placing ourselves at the heart of the European project, because the climate emergency demands it.
