Question to the Home Office:
To ask the Secretary of State for the Home Department, how many people were incorrectly investigated as a result of immigration officials believing that they were living illegally in the UK in each of the last five years.
This data can not be extrapolated from our systems and would necessitate a case by case examination across multiple IT systems. The information requested could only be provided at disproportionate cost. All of Immigration Enforcement's operations are intelligence led and are only conducted when information suggests that they will encounter an illegal migrant.
