I will get to the Silhouette case later on. Although I will comment on it briefly, it might be that I need to write in greater detail.
Going back to the SI before us, it is clear that it maintains the status quo as far as possible. Regulation 2 ensures that the domestic exhaustion framework remains the same after exit. That delivers as far as possible a continuation of the current regional exhaustion regime. That is the legal clarity we can provide the moment. I cannot take the noble Lord any further, other than to say that we have been clear that this is a temporary fix and we will revisit it when we have gathered the evidence we need.
