Question to the Home Office:

To ask the Secretary of State for the Home Department, what proportion of people had their passports checked on exiting the UK at (a) Dover and (b) all UK airports, seaports and ferry ports in (i) 2013, (ii) 2014 and (iii) 2015.

Embarkation controls were abolished in two phases in 1994 and 1998, as the paper-based checks were deemed outdated and checks were not carried out on all modes of transport. Consequently the Home Office does not hold the data requested.

Since April 2015 exit data has been collected by carriers from all scheduled international commercial services departing the UK from air and sea ports and from international rail stations, except those services not within the scope. Departure data is collected by carriers and port operators and transmitted to Home Office systems, where work takes place to match it to arrival data, visa conditions and other information as appropriate.
