Question to the Home Office:
To ask the Secretary of State for the Home Department, what proportion of immigration detainees who are (a) foreign national offenders (b) other detainees had been in immigration detention for (i) 28 days or fewer and (ii) over 28 days at the end of quarter 2 of 2018.
Providing the information requested would require a manual check of individual records which could only be done at disproportionate cost.
The Home Office publishes the number of Foreign National Offenders currently detained. The data can be found in the quarterly Immigration Enforcement Transparency Data. https://www.gov.uk/government/publications/immigration-enforcement-data-november-2018
The Home Office also publishes data on immigration detention, including the length of detention of those leaving detention (table dt_06_q) and the length of detention of those in detention at the end of each quarter (table dt_11_q). The data can be found in the detention tables in the latest Immigration Statistics, year ending September 2018, quarterly release.
I will be writing to the Right Honourable Lady separately concerning this as it links to a request she has made as chair of the Joint Committee on Human Rights.
