This article organizes publicly available information into a single account. Where it describes an arrest or an ongoing investigation, that reflects only one stage of criminal procedure and does not mean guilt has been established (the presumption of innocence applies). We will update this article as new information becomes available, including the outcome of prosecution, non-prosecution, or trial. This article is not intended to unfairly disparage any individual, group, nationality, ethnicity, or belief, and aims to provide objective, fact-based information.
The UK Home Office published illegal working enforcement statistics for January-June 2026 on August 19, 2026. During that period, enforcement teams carried out 7,270 visits, up 31% year-on-year, and made 4,756 arrests, up 20%, both record highs for the period. The Home Office described the first half of the year as "the most successful start to a year on record for illegal working enforcement activity." Civil penalties were issued against 1,238 businesses totaling more than £74 million. There were 10 closure notices and 55 reviews of alcohol and late-night refreshment licenses.
By sector, restaurants, takeaways and cafes saw the most activity, with 2,195 visits and 1,589 arrests, followed by food, drink and tobacco retail (1,409 visits, 389 arrests) and the beauty industry (1,041 visits, 648 arrests). The warehousing, distribution and delivery sector stood out for its sharp rise, with 635 visits and 635 arrests, up 147% and 70% respectively year-on-year. Over the two years from July 2024 to June 2026, enforcement teams conducted nearly 25,000 visits (up 111%) and made approximately 17,000 arrests (up 122%) compared with the preceding two-year period.
Current status: The nationality breakdown of those arrested for illegal working, and the extent to which they have since been removed from the country, remain unclear as of this writing. This article will be updated as further details emerge.
While not directly related to Japan, the practice of a government regularly publishing illegal-working enforcement results broken down by sector and region resonates with Japan's own publication of foreign national crime statistics by its police and justice ministries (related coverage), offering a reference point for how to make the effectiveness of illegal-employment countermeasures visible to the public.
Editorial Perspective
The Technical Intern Training Program is set to be replaced by the new Employment for Skill Development system in April 2027 (related article), and developments like this one can be seen as part of the institutional design process during that transition. Expanding acceptance also requires resolving practical issues such as broker problems in sending countries and building proper oversight systems among accepting employers. For the new system to work as intended rather than merely on paper, it will be important to continue examining how it actually operates once implemented.
