The Ombudsman has said any body set up to investigate the Gardaí must have the same powers that his office enjoys.
Publishing his annual report this morning, Kevin Murphy, said those essential powers included independence from political interference and absolute privilege.
More than 15,000 people contacted Mr Murphy's office last year, which is double the amount of the previous year.
Two and a half thousand went on to make valid complaints, mostly about civil service departments, local authorities or health boards.
The Ombudsman said both the public and public bodies had become more aware of his role. Mr Murphy said he was pleased that all the main political parties had now accepted the principle of independent investigation of complaints against the Gardaí.
He said it did not matter what such a body was called but it had to have the same powers that he had, including complete independence, security of tenure and privilege.
Mr Murphy also criticised the fact that he did not have the power to investigate complaints against public Voluntary Hospitals.
He said his office was investigating the fact that the Revenue Commissioners do not compensate people who are overcharged on income tax.
