The situation the noble Baroness is describing will obtain if the Prime Minister’s deal goes through and we go into an interim transition period. It is certainly the situation that would obtain if we go into the backstop. We would be a rule taker. We would have no say in the making of the tariffs but we would have to apply them. We would not be consulted; we would be notified.
The amendment refers to “a” customs union. We have never attempted to work out what kind of customs union the EU would be prepared to agree with us. We have never done that because the Prime Minister’s rash red line ruled it out. We are now going into the worst possible case, if the deal goes through, of being absolutely a rule taker and absolutely not in the European Council, as correctly described by the noble Baroness. However, that is not what the amendment is asking for. It is asking for the negotiation of a real customs union between the United Kingdom and the European Union.
