Consulting firm Principia Advisory has been appointed to conduct a retrospective review of KPMG’s whistleblowing system, with the findings to be made public.KPMG said it would strengthen its internal controls, including updating its whistleblower policies, reviewing its misconduct and disciplinary framework, tightening ethical safeguards and mandating additional training on client confidentiality, privacy and information protection.The firm said the reforms would sit alongside an independent review commissioned by the Commonwealth Department of Finance, which it said it would fully cooperate with.Interim chief executive Stan Stavros said the firm had fallen short of expected standards."The decisions announced today are necessary and immediate We did not meet the standards expected of us, and we recognise the impact this has had on the whistleblower, our people, our clients and the community," he said."Trust will only be rebuilt through sustained action and demonstrable change
