I thank my noble friend for that contribution. I also respect the National Preparedness Commission and know how useful it is because I was, fairly briefly, a not particularly active member of it. It is interesting that somebody in the media already thinks they know who is responsible. One should wait for the in-depth and comprehensive review from Heathrow Airport itself and the National Energy System Operator to find that out. In particular, they must between them look at whether complete closure was the only option, or whether some partial closure could have been achieved with less disruption. The direct answer to whether the department has powers to change the risk appetite of an airport operator rests with the Civil Aviation Authority, which is the economic and safety regulator for airports. The Secretary of State has, of course, been in touch with the CAA, which will look closely at the work to be done by Heathrow Airport in the Kelly review. When the CAA receives that report it will then be able to take a view on the appropriate level of risk appetite and the amount of money that needs to be spent to assuage that risk. The CAA is the authority that should, in due course, take a view, and I am sure that it will.
