Question to the Home Office:

To ask the Secretary of State for the Home Department, how many passengers have travelled to the UK on routes connected to the Semaphore system since 2009.

The Home Office collects Advance Passenger Information for passengers who
travel to and from the UK on routes connected to the Semaphore system. The
passenger figures for journeys to the UK are only available from May 2010.

The estimated number of passengers who travelled to the UK on routes connected
to the Semaphore system from May 2010 to the end of 2014 is 350 million.

Obtaining data older than five years is currently against data protection
legislation unless it is specifically for a visa related query.
