The UK government has imposed stricter rules in a nationwide crackdown that led to the arrest of hundreds of undocumented migrants, many of whom had turned to delivery work, between 20 and 27 July 20, the interior ministry said Saturday.

During the week-long operation, authorities stopped and questioned 1,780 individuals, detaining nearly one in five. Fifty-three people were identified as under review for asylum support, which could potentially be revoked. The operation focused on migrants working without proper permits, particularly in the gig economy, where food delivery jobs are popular.

Authorities also impounded 71 vehicles, including 58 e-bikes, and seized £8,000 in cash and 460,000 illicit cigarettes.

Meanwhile, civil penalties were issued to 51 businesses accused of employing illegal workers.

The government said the crackdown is part of a broader enforcement strategy to restore public trust, backed by an additional £5 million in funding.
