I am very happy to explain again that this SI sets out our position in relation to EU operators coming into the UK; there is no restriction on cabotage in that regard. However, the EU regulations restrict cabotage, which is why they are asymmetric. We still need to reciprocate the access, which is what this SI does.
I hope that I have answered most of the questions raised. If I have missed any, I shall follow up in writing. This instrument is needed to allow the continued operation of international bus and coach services in the event of no deal until such time as fully reciprocal arrangements are in place.
