UK turns to criticised but powerful China-style technology to hunt visa overstayers as Nigerians, Indians and South Africans face tougher checks

The UK is preparing to expand its use of live facial recognition technology to hunt visa overstayers and identify people who have breached immigration conditions, potentially deploying cameras at transport hubs, ports and major public events. The plans could bring Nigerians, Indians, Pakistanis, South Africans and other immigrants under greater scrutiny as the government considers using biometric surveillance to strengthen immigration enforcement.
