Figures for 2009 are not yet available. Figures from 1997 to 2000 inclusive represent detections at the border only. Those from 2001 to 2008 inclusive detail detections at the border and those made in country by caseworking offices and enforcement officers. They do not include the numbers of inadequately documented passengers denied boarding by commercial carriers overseas working in conjunction with UK Immigration Liaison Officers and Managers (formerly Airline Liaison Officers) from the Risk and Liaison Overseas Network. Some of these passengers will have held false documents but precise figures for the numbers denied boarding for this reason are unavailable.
