No, I am not referring to designated officers at port with the ability to detain. The provision refers to teams of immigration officers who carry out enforcement activities, not necessarily at a port at all and who are able to arrest in relation to an immigration offence.
In terms of officers designated at port, the purpose of that designation—as I understand it—is that they can detain individuals for up to three hours who are not necessarily being detained in relation to an immigration offence and who may be a British citizen. That is somewhat different. If the hon. Gentleman is asking about the training for officers at ports who are exercising the powers that he refers to under clauses 1 to 4, I would have to undertake to write to him. That is not the same as the powers being discussed in this clause nor would these immigration officers receive the same training.
