I thank my hon. Friend for the question and for her thanks to NESO, which has done a comprehensive job on this report in a fairly short space of time. There are lessons to be learned for Heathrow, and it will be learning those lessons. I am in communication with the Transport Secretary, who of course has immediate responsibility for Heathrow as a piece of critical national transport infrastructure. It is worth saying that its back-up generators did operate in the way they were supposed to, but Heathrow is a huge piece of infrastructure, and it is not intended that those back-up processes would continue to run normal operations in a huge airport beyond the immediate situation of being able to land planes safely and ensuring other critical systems within the airport. The question Heathrow has to answer is on having three points of electricity generation coming into the airport. It clearly needs to look at the way the network is configured and take forward the wider question of its resilience and ability to adapt to such situations. The Government have an incredibly important role, as my hon. Friend rightly says, and we will do all we can to ensure that National Grid is doing its bit, that the distribution operator is doing what it needs to do, and that Heathrow Airport Ltd is also meeting the expectations that we would expect from our most important piece of transport infrastructure.
