Carbon tax just brutal politics: Credlin

Peta Credlin admits the climate change policy under Julia Gillard's Labor government was never a carbon tax, but the coalition used that label to stir up brutal retail politics.

Credlin, the former chief of staff to Tony Abbott when he was prime minister and now a political commentator for Sky News, said the coalition made it a "carbon tax" and a fight about the hip pocket rather than the environment.

"That was brutal retail politics, and it took Abbott six months to cut through and when he did cut through Gillard was gone," she told Sky News on Sunday.
