Flight details of more than 70 celebrities 'leaked by Virgin employee' It was unclear last night whether she actually caught the plane but a former head of the royal protection branch warned that security could have be "compromised." Lawyers for some of the celebrities targeted were last night considering legal action while other said the details should be passed to the Leveson Inquiry, which is examining media ethics. A Virgin Atlantic employee resigned on Thursday and the company has launched a full investigation. Princess Beatrice was expected on a flight to Newark, New York in March 2011, according to the emails, seen by the Daily Telegraph. It was around that time that her father, Prince Andrew, was facing questions over his links to Jeffrey Epstein, the disgraced financier and convicted paedophile. Dai Davies, former head of royal protection, said of the leaked flight details: "It could be a security risk and is a concern. The implications are that other Royals, senior ones and who are at greater risk from terrorists or fixated people, could have been compromised. Lawyers for footballer Ashley Cole, another target, said he was considering legal action over possible breaches of data protection or potential confidentiality breaches between an airline and their passengers. Graham Shear of Teacher Stern confirmed that Cole had taken the flights mentioned and was photographed by Big Pictures on his return from LA. He said: "We have not been contacted by Virgin Atlantic but we anticipate they will be in touch with us. We are awaiting further information and once that is assessed we will consider bringing proceedings. Legal sources close to some of the other alleged victims urged Lord Justice Leveson, who is conducting a public inquiry into the press, to consider the matter. One said: "This is exactly the sort of unethical activity that the inquiry should be examining. This is not just tipsters telling picture agencies when they spot a celebrity but payments to induce a breach of contract. It is an extremely worrying development.
