According to the data, 1,370,820 NI numbers were given to overseas staff from July 2007 to June 2009, despite Gordon Brown's pledge to maintain 'British jobs for British workers' just before he became prime minister.
Sayeeda Warsi, communities spokesperson for the Conservatives, said the report show the 'chaos' which is afflicting the UK's immigration system.
'These figures show that all the tough talk about protecting British jobs was just hot air. We can't go on like this,' she commented.
Ms Warsi added that the UK's workers would benefit if further steps were taken to control the immigration system and more investment was made in the education and training of British employees.
The British Chambers of Commerce recently called for the government to scrap the one per cent rise in employers' NI contributions and suggested it is replaced with an increase in VAT.
