The director of the Serious Organised Crime Agency (Soca), Trevor Pearce, is being urged to publish a document listing clients of rogue private investigators. MP Keith Vaz said he would publish the list by midday today if Mr Pearce did not.
The Information Commissioner has been called to give evidence to MPs over the publication of a controversial list of clients of rogue private investigators. Christopher Graham will appear before the Home Affairs Select Committee tomorrow.
"Following representations that the Committee has received from the Information Commissioner we have called him to give evidence to the Committee on Tuesday.
"We will hear his views on the issue of the publication of the Soca list and related matters."
SOCA provided Mr Vaz's committee with the list - containing 102 firms and individuals, including blue chip companies, law firms and financial services groups - on condition that the names are not revealed, sparking a row over transparency.
The Information Commissioner has written to the chairman of the Home Affairs Select Committee urging "patience" after he threatened to publish the names of clients of rogue detectives, compiled by the Serious Organised Crime Agency.
Writing in a blog Mr Graham said he has written to Keith Vaz urging him not to go through with his threat to publish the names of the clients on the list by midday today.
"It's not clever to start a criminal investigation by publishing the names of everyone and everything you're investigating.
"That's why we've stated we're not publishing the list at this stage, and why I've written to Keith Vaz MP to urge similar patience on the part of his Select Committee.''
