If a proposal requires planning permission, Scottish ministers play their usual role within the planning system. Whether a proposal requires planning permission will depend on the particular circumstances of the case.
I am blessed with many things, but a requirement that Mr Cairns be answerable to me is not one of them. He is accountable to Westminster for his answers. However, the position on this issue is clear: defence is a reserved matter, and planning is devolved. As I said, if a proposal requires planning permission, the Executive might become involved in the decision-making process.
