Welcome to the IOCCO website. I was appointed as Interception of Communications Commissioner in January 2013 by the Prime Minister under Section 57(1) of the Regulation of Investigatory Powers Act (RIPA) 2000. My function is to keep under review the interception of communications and the acquisition and disclosure of communications data by intelligence agencies, police forces and other public authorities. I am required to make an annual report to the Prime Minister with respect to the carrying out of my functions.

We are aware of the Press Gazette's 'save our sources' petition and understand the concerns raised about the protection of journalistic sources so as to enable a free press.

Our publication sought to highlight and explain the law in relation to Part I Chapter 2 of RIPA and to importantly explain how complaints are dealt with. On this latter point Parliament has indicated (see section 65(4) of RIPA) that the Investigatory Powers Tribunal is the appropriate forum for any complaint by a person who is aggrieved by conduct under Part I Chapter 2 and our office may give assistance and / or advice when requested by the Tribunal in line with section 57(3).

A large number of these errors have led to communications data being acquired relating to members of the public who had no connection to the investigation or operation being undertaken. SROs have been instructed to develop, implement and robustly enforce measures to minimise the repetition of such errors.
