[holding answer 10 March 2009]: The Home Office has not commissioned or carried out any further research on the likely number of illegal immigrants in the UK since the Home Office Online Report 29/05, “Sizing the unauthorised (illegal) migrant population in the United Kingdom in 2001” was published in 2005.
We are determined to bear down on illegal immigration both on and after entry to the UK and as part of the Government’s 10-point plan for delivery by 2010 over 95 per cent. of non-EEA foreign nationals will be counted in and out of the country. This is part of a sweeping programme of border protection which also includes the global roll-out of fingerprint visas, watch-list checks for all travellers before they arrive or depart from the UK and ID cards for foreign nationals.
