Shadow Minister for Indigenous Australians Jacinta Nampijinpa Price says it is “no surprise” Indigenous academic Marcia Langton is going down the path of calling No supporters 'racist'.

Sky News Political Editor Andrew Clennell revealed on Wednesday a video that was filmed in July of the professor labelling those against the Voice "racist" and “stupid”.

“I’m no stranger to attacks from Marcia – she has attacked me, she has attacked my mother before,” Ms Price told Sky News host Peta Credlin.

“She has made some pretty horrible derogatory claims about the both of us – she's made it about many people.

“It’s no surprise that she continues down this particular path.”
