MP Chris Bryant and acting deputy commissioner for the Metropolitan Police John Yates are due to appear in front of the Home Affairs committee today to answer questions about the Met’s investigation into the News of the World phone-hacking affair.

Earlier this month, Bryant accused Yates of misleading the committee previously in claiming that the number of of phone-hacking victims was between eight and 12.

According to a report by Politics.co.uk, Byrant criticised Yates’ argument that the Crown Prosecution Service’s definition of phone hacking was limited to voicemails intercepted before they were listened to by the intended recipient.

“Yates misled the Committee, whether deliberately or inadvertently. He used an argument that had never been relied on by the CPS or by his own officers so as to suggest that the number of victims was minuscule, whereas in fact we know and he knew that the number of potential victims is and was substantial.”

Last week, appearing before the culture, media and sport select committee, Yates said Bryant was “materially wrong” to accuse him of misleading the committee.

In related news, the Media Guardian reports today that the News of the World’s computers “have retained an archive of potentially damning emails, which hitherto it had claimed had been lost”.

The millions of emails, amounting to half a terabyte of data, could expose executives and reporters involved in hacking the voicemail of public figures, including former deputy prime minister John Prescott, actor Sienna Miller, and former culture secretary Tessa Jowell.

The Guardian reports that MPs on the home affairs select committee are likely to question Yates about these emails later today. You can watch the committee session via Parliament Live TV here.
