A group of eminent Australians are calling for an end to delays in establishing a federal anti-corruption body.

The open letter addressed to Prime Minister, Scott Morrison, said the government kept the people waiting for 922 days for a federal integrity commission.

Mr Morrison announced plans for a Commonwealth Integrity Commission in December 2018, but was stalled during 2019 and was not revived until late 2020.

David Harper, a former judge on the Victorian Supreme Court of Appeal and a signatory on the letter said the delays can no longer be tolerated.
