Question to the Home Office:

To ask Her Majesty's Government what estimate they have made of the failure rate of biometric passport gates at UK airports; and what was the total amount of delay resulting from such failures in 2016–17.

Protecting the UK border is, and always has been, of paramount importance to this Government. It has never been government practice, for reasons of national security, to comment on operational issues relating to border security. This includes offering commentary on the performance of border systems and of ePassport Gates specifically.
