I am grateful for that ornithological outing from my right hon. Friend. The first thing to say is that Operation Yellowhammer absolutely does exist. It is the reasonable worst-case scenario, and the planning assumptions, as the National Audit Office has outlined, are those which we seek to, and have taken steps to, mitigate. She also referred to Operation Kingfisher, which is the programme led by the Treasury and the Department for Business, Energy and Industrial Strategy in order to ensure that we can intervene as appropriate in particular sectors in the event of no deal. I am afraid that there is no operation dodo, although I can well understand why the Independent Group for Change would be interested in such an exercise.
