Soca, Scotland Yard and the Information Commissioner, Christopher Graham, have requested that none of the names on the list are published.
Mr Graham appeared before the Committee last month and is to provide an update on 8th October.
In his most recent letter, Mr Graham said:
The Public Accounts Committee had threatened to release a full list of 102 of those involved.
Among those suspected of dealing with private investigators who broke the law:
- Five retailers
- Four legal firms
- Three insurance companies
- Two financial businesses
- One construction firm
- One security company
A further three private investigators were also included.
Information Commissioner Christopher Graham and his office were initially handed a list of 98 clients of corrupt private detectives by the Serious Organised Crime Agency (Soca).
Among them, 12 firms on the list were found to be no longer trading, while the Information Commissioner's Office (ICO) was awaiting further information on another 11.
A total of 19 clients of rogue private eyes will be investigated for illegal activity, the data watchdog has confirmed.
In a letter to Keith Vaz MP, Information Commissioner Christopher Graham said 125 victims were believed to be affected by the companies and individuals under criminal investigation for data protection breaches.
MPs had threatened to release a full list of 102 of those involved if action was not taken.
A list of clients of rogue private detectives will not be published by MPs "for the time being" after the data watchdog intervened.
Information Commissioner Christopher Graham urged the Home Affairs Select Committee not to publish a list of 102 organisations and individuals who used rogue investigators while his office conducted its own investigation.
Committee chairman Keith Vaz MP said: "The Information Commissioner has given the committee an explicit commitment that he will pursue this matter to its appropriate end and that the victims will receive justice."
Vaz said Graham would appear before the Committee after his "scoping exercise" so that MPs could assess whether the investigation "fulfils all that is required".
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.
Speaking last night, Mr Vaz said:
"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.''
The head of the Serious Organised Crime Agency (Soca) has refused to release a document listing clients of rogue private investigators, despite an ultimatum from MPs.
Trevor Pearce was told by the head of the Home Affairs Select Committee he has until midday today to publish the list, or have it published by the committee.
Scotland Yard has confirmed nine names have been withdrawn from a controversial list of around 100 clients of rogue private detectives as they are still being investigated.
He added that five of the names relate to Operation Tuleta, the force's probe into computer hacking and other alleged privacy breaches, while four relate to other ongoing investigations.
The names of around 100 firms and individuals who allegedly used corrupt private investigators was handed from Soca to the Committee earlier this year on condition it was not published.
Nine names have been removed from a controversial list of clients of rogue private detectives on the eve of its publication as they are subject to live investigations, Scotland Yard has said.
The list, which includes law firms, insurance companies, financial services groups and celebrities, is expected to be released on Monday by the Home Affairs Select Committee.
It follows threats from chairman Keith Vaz after the director general of the Serious Organised Crime Agency (Soca) refused to release the document despite an ultimatum from MPs.
