We continually test our plans and our resilience. As I set out in response to a previous question, barring a very exceptional circumstance, the Business Secretary and I have confidence in our power networks. The hon. Gentleman asks what the United Kingdom Government are doing. I gently say to him that it is because of the strength of our United Kingdom that we have been able to provide over £50 billion-worth of support for families up and down the country to keep their energy bills under control this winter. An independent Scotland simply would not have that kind of firepower.
