If a patient is not registered, they are not registered. If a patient goes as a temporary resident—as I think the term used to be; I am not sure if it still is—to see a particular doctor, a general practitioner, they are then registered for the period of the temporary residence, which from memory is, or at least used to be, one month, and which may be renewable for the purposes of that treatment.
To deal with the broader aspects of the noble Lord’s question it might be worth making the further point, while I am on my feet, that it is very difficult to imagine that a patient would be in the situation described in the Bill but had not been treated for at least six months by a practitioner, such as the practitioner who was treating their cancer. That is the general experience that people have.
