The BBC has stopped its staff from using BlackBerrys after a flaw in BlackBerry Enterprise Server meant workers at the Beeb received portions of emails intended for colleagues.

The service was suspended after BlackBerrys, used by 300 of the corporation's execs who spend the most time out of the office, started receiving fragments of emails meant for their co-workers.

A spokesman for the BBC said the problem was first spotted by one of the BlackBerry users.

The spokesman said: "We immediately suspended the service and the service remains suspended until we get assurances that it is secure."
