Question to the Home Office:

To ask His Majesty's Government how many (1) undocumented migrants, and (2) refugees, entering the UK in the last five years were nationals of (a) European, (b) African, and (c) Asian countries.

In your question we have interpreted ‘undocumented’ as meaning people who are detected entering the UK who do not carry valid documentation which entitles them to come to the UK, and therefore are termed ‘irregular’ arrivals.

The Home Office publishes data on irregular arrivals to the UK in the quarterly Irregular Migration to the UK release which can be found on gov.uk. Data on small boat arrivals by nationality are published on gov.uk.

If by ‘undocumented’ arrivals you meant undetected arrivals, we cannot provide this as by the very nature of these individuals going undetected, we hold no information on them. Please see the ‘About the statistics’ section of the Irregular Migration to the UK release on gov.uk for more information on what the statistics do and do not include.

Information on asylum cases is published in the Immigration statistics quarterly release on gov.uk.
