The Coalition's legislative agenda has been derailed for the second time in days, with Prime Minister Scott Morrison announcing his government has pushed back its plans to outlaw religious discrimination until next year.

The delay follows a high-powered intervention from religious leaders, including Mr Morrison's Pentecostal movement, who threatened to withdraw support for the contentious religious discrimination bill unless greater freedoms were granted to Australians of faith.

Attorney-General Christian Porter initially said the bill would be introduced in October, and then by the end of 2019. On Saturday, Mr Morrison said it would now come to Parliament next year, with a second draft to be released for consultation soon.

"What Australians believe is really important to them and to me," he said in a video recorded in front of a Christmas tree.
