The prime minister has again rejected claims he made racist comments during a 2007 preselection battle for the NSW lower house seat of Cook.
Outgoing Liberal Senator Concetta Fierravanti-Wells last week made the accusations under parliamentary privilege, claiming Scott Morrison told party members they couldn't have a Lebanese person as a candidate.
The Sydney Morning Herald on Saturday published details from two statutory declarations signed in 2016 about the 2007 preselection campaign.
The declarations claim Mr Morrison said the Liberal Party should not back his main opponent because of his Lebanese background and rumours he was a Muslim.
Mr Morrison on Wednesday denied Senator Fierravanti-Wells' initial accusations, labelling the comments as "rubbish".
The prime minister continued to deny the claims on Saturday, replying "no" three times when asked by reporters if he made the comments.
One Nation Senator Pauline Hanson and Independent Senator Jacqui Lambie this week joined Senator Fierravanti-Wells in criticising Mr Morrison, describing him as "unpleasant" and a "bully".
But senior Liberal party members showed their support for the PM, with Senator Jane Hume saying Mr Morrison was "extraordinarily supportive".
