Question to the Home Office:

To ask the Secretary of State for the Home Department, how many exit checks were conducted at each UK border point of exit in each of the last 12 months; and how many of those checks resulted in (a) temporary and (b) permanent detention by police or other authorities.

Since 8 April 2015 departure data has been collected on all scheduled commercial services departing the UK from air and sea ports and from international rail stations except those services not within the scope of the exit checks programme.

Border Force hold data for outbound alerts issued by Border Force at the National Border Targeting Centre (NBTC) where feedback has been received, such as those which have been progressed for pre-departure intervention.

A variety of agencies, including Border Force, undertake outbound interventions, as a result of this various activity there is no single record held on their respective outcomes.
