Question to the Home Office:

To ask the Secretary of State for the Home Department, how many clandestine migrants have been identified at (a) the UK's seaport and (b) the Port of Tilbury in each year since 2000.

The following detections of clandestine migrants have been made across all UK sea ports since 2011 (to obtain data pre-2011 would be at disproportionate cost): 692 detections in 2011, 568 in 2012 and 678 in 2013.

In order to ensure the integrity and security of the UK border, Her Majesty’s Government does not comment on port specific statistics.

The figures quoted are management information, subject to internal quality checks and may be subject to change. The figures include those detected at a sea port and on ferries.
