Labor demands new Bishop investigation

Labor has accused the Finance department of bias, and is demanding the investigation of Bronwyn Bishop be carried out by another department.

Labor's waste watch spokesman Pat Conroy says he has no confidence the department can investigate the Speaker's alleged misuse of taxpayer funds, after the head of the Finance department Jane Halton reportedly dismissed the scandal as sexist double standards.

He has written to Prime Minister and Cabinet department secretary Michael Thawley demanding the investigation be handed to another department or the Australian Federal Police.
