Information commissioner at Leveson Inquiry
Data protection laws covering illegally obtaining or using personal information are being breached every day, the Leveson Inquiry has heard.
UK information commissioner Christopher Graham said efforts to deal with this "real challenge" were being frustrated by the press.
He said data abuses were not just about the press but NHS workers, bank clerks and private investigators.
He said he did not have the resources to investigate everything that people want him to.
