The system will cover 133 countries, three-quarters of the world's population, and has already uncovered 10,000 visa applicants connected to earlier immigration cases and asylum requests and detected 500 cases of identity swapping.

This includes a Nigerian man trying to enter the UK under a different identity after serving an eight-month prison sentence.

The database has been rolled out in stages since last year and will be fully up-and-running by the end of January, three months ahead of schedule and costing only £37m to set up - nearly half of its original £70m budget.

Immigration minister Liam Byrne congratulated Border and Immigration Agency officials and set out 10 milestones to strengthen border protection this year, which include introducing compulsory ID cards for foreign nationals who want to stay in the UK and introducing spot fines for employers not carrying out right-to-work checks.

He said in a statement: "The public wants stronger borders. They want us to shut down the causes of illegal immigration and hold newcomers to account, deporting rule breakers where necessary."

Byrne added: "They also want a compassionate system, which makes and enforces decisions fast when we have obligations to honour."
