Avon and Somerset Police's Chief Constable Colin Port and Detective Chief Inspector Phil Jones have given evidence to the Leveson Inquiry into press ethics - in connection with the Jo Yeates murder investigation.

Mister Port accepted there had been an "inadvertent leak" about Jo's landlord Christopher Jefferies' arrest as a result of a 'genuine error' but called suggestions officers gave off the record briefings to journalists outrageous and abhorrent.

He added he feels it important that journalists hear both side of the story on both a formal and informal basis - but doesn't consider media relations and hospitality a problem for the Force.
