News tips and information

If you have information relating to Deloitte, PwC, EY or KPMG — including audit quality, regulation, litigation, governance, firm culture, partnerships or other matters of public interest — please get in touch.

Current and former employees, partners, clients and others with direct knowledge of events are particularly welcome to make contact.

Confidential information

If you are considering sharing sensitive or confidential information, please make initial contact without sending confidential documents or highly sensitive material.

We can discuss an appropriate method of communication before any such material is shared.

Big4News will treat requests for confidentiality seriously, but ordinary email should not be regarded as a secure or anonymous communications channel.
