Peta Credlin swings Sky News role

Peta Credlin will join Sky News' political commentary team and hopes to help ordinary Australians to better understand their choices.

Tony Abbott's controversial former chief of staff Peta Credlin has secured an on-air role as a Sky News commentator for the upcoming federal election.

Credlin has told News Ltd she hopes "to help ordinary Australians better understand" their choices at the polling booth and to add some insider value to their political team.

But she's ruled out a permanent move into the media or a return to politics as an MP.
