GCHQ Monitored Own Staff Excessively

An official watchdog has said GCHQ, the UK's electronic eavesdropping agency, has been found to be spying too much on its own staff.
Sir Mark Waller, the intelligence services commissioner, reveals in his annual report that GCHQ reported one error to him last year when it was found that an internal monitoring system, which keeps an eye on staff communications, was capturing an unauthorised amount of information.
