The hon. Gentleman raises two important points. First, in respect of the winter weather, the Cabinet Office is keeping a close eye on it. Indeed, I have been briefed on the situation. On the wider situation in relation to energy supply, I am working closely with the Secretary of State for Business, Energy and Industrial Strategy, my right hon. Friend Grant Shapps. He and I have strong confidence about the resilience of the UK power networks and, excepting a very exceptional circumstance, we are confident that we will continue to supply throughout the winter.
