Dozens of adult migrants posed as children to get into Britain, a former Border Force chief admitted last night.
After the Jungle refugee camp in Calais closed last year, 750 "vulnerable minors" were granted sanctuary in the UK as part of a deal struck with France. Concern was raised at the time that a number of them appeared to be over 18.
Tony Smith, former director-general of the UK Border Force, said: "I am not confident all the vulnerable minors brought over from Calais were children. In fact, I am confident some of them were not and were actually adult economic migrants posing as children.
"Some would have sworn on their mothers' lives they were only 16 even though they had a beard and were balding.
