The noble Lord asks a fair question. However, as he probably knows, it has never been government practice, for reasons of law enforcement, to comment on operational issues relating to border security and immigration controls. This includes offering commentary on the performance of border systems and e-passport gates specifically. The e-gates process passengers arriving in the UK, and provide a secure border check on approved travel documents, and refer passengers to an officer if required. The current e-gate estate was upgraded in 2021. Incidents impacting the availability of e-gates are proactively managed, and lessons are learned. They have certainly been learned from this most recent incident.
