[holding answer 21 April 2008]: Since the phasing out of border controls in 1994, no Government have ever been able to produce an accurate figure for the number of people who are in the country illegally and that includes illegal workers. By its very nature it is impossible to quantify accurately and that remains the case.
As one of the Government's 10 substantive changes to the border and immigration system in 2008 we will count in and out the majority of foreign nationals. This will build on the successes of our early testing of the e-Borders programme (Project Semaphore) which already covers over 30 million passenger movements and has led to 18,000 alerts and more than 1,500 arrests.
This is part of a large-scale programme of reform to border protection which also includes the global roll-out of fingerprint visas, compulsory watch-list checks for all travellers from high-risk countries before they land in Britain and ID cards for foreign nationals.
