I am grateful to the Prime Minister for giving way. I was puzzled by her claim that the joint instrument is of comparable legal weight to the withdrawal agreement. I am sure she will be aware that, as a matter of international law, the withdrawal agreement is a treaty. The joint instrument is not a treaty; it is merely what is known as a document of reference, which can be used to interpret the withdrawal agreement. Would the Prime Minister therefore care to rephrase her assertion that the joint instrument is of comparable legal weight to the withdrawal agreement, because that is simply wrong as a matter of law?
