Days after a rout in Britain over top secret intelligence files left on a train, it has emerged more confidential papers were lost on the same day. Earlier this week, a classified file was handed to the BBC containing intelligence assessments about Al-Qaeda. Now The Independent on Sunday newspaper says it was handed a separate sect of confidential documents. Laura Kuenssberg reports.

Files relating to money laundering and terrorist financing and drug smuggling were discovered by a nember of the public on a train bound of London's Waterloo station. A spokesman for the Treasury says there is extremely concerned about what's happened and will be taking steps to ensure it doesn’t happen again. This discovery may be on a smaller scale than recent breaches but it suggests despite repeated government promises the guarding of sensitive data is not taking seriously enough.
