London: Due to a widespread issue affecting the automated border control gates that scan passports upon arrival, passengers flying into Britain experienced significant delays after landing at airports on Saturday. Images shared on social media showed lengthy lines at London's Heathrow and Gatwick airports with hundreds of people, and angry travellers lamented having to wait for hours in line. A spokesperson for the British government's interior ministry, which is in charge of border control, said, "We are aware of a nationwide border system issue affecting arrivals into the UK."

All passengers must go through manual checkpoints as a result of the disruption, which occurs during a busy time for travel in Britain with a spring bank holiday on Monday and a half-term break for schools the following week.
