One of the most prominent Indigenous figures in recent Liberal politics says the Voice to Parliament will be hamstrung if it cannot directly advise ministers, saying his former colleagues should have "no reason to be afraid" of the proposal.
Speaking publicly for the first time since resigning his membership, Ken Wyatt told 7.30 it had been a "hard decision".
"I had to weigh up my love of the Liberal Party and its values, and what it stands for, against a stubborn position of not wanting to give Aboriginal people a seat at the table," Mr Wyatt said.
