The hon. Lady asks an important question. I was in touch with the National Energy System Operator yesterday following the events in Spain and Portugal—the UK was not affected. NESO and my Department take this incredibly seriously. I would also add, given that there has been some comment on this, that we should not jump to conclusions about what happened. Let us see what happened and the reasons for it, and then learn the lessons.
