Operation of Air Services (Amendment etc.) (EU Exit) Regulations 2018

Before the Minister sits down, if the document that we have had from the European Commission, specifically the section on air transport, represents the Commission’s stance in the event of no deal—as I understand it, the Minister said we were in discussions with it—what is the latest date by which something has to be agreed so that it is effective from 29 March? Presumably what has been listed here by the European Commission as its position cannot be agreed the day before, and presumably it has to be agreed before then to come into operation on 29 March. So what is the latest date, realistically, by which something has to be agreed?
