South Australian Senator Kerrynne Liddle has revealed numerous signatories on the Uluru Statement from the Heart were "surprised" to see their name on the document calling for an Indigenous Voice to Parliament, says Sky News host Amanda Stoker.

"Those people told Senator Liddle they were 'unhappy' to be seen as endorsing the statement," Ms Stoker said.
