London, July 22: British airports are at risk of terrorist attack from a “threat within,” a report by a former bureaucrat will warn today.
The alert is raised in a security review by former civil servant Stephen Boys Smith.
He demands a crackdown on thousands of people working in shops, cafes and baggage depots.
An insider said: “It is possible they can have a criminal past in another country that is not picked up.”
Experts claim that hundreds of foreign workers with a criminal past may have landed airside jobs.
British staff and pilots undergo rigorous checks, but offences committed overseas often go unchecked, The Sun reported.
