Peta Credlin's wish to be able to use her own voice is about to come true with one of the most talked about figures of the Abbott government set to join Sky News as an election commentator ahead of an expected double dissolution election on July 2.

Tony Abbott's former chief of staff has told News Corp she has been offered several media jobs since departing the prime minister's office in September but chose Sky because she respects their team of journalists, which includes David Speers, Kieren Gilbert and Laura Jayes.

In the immediate days after the change of leadership to Malcolm Turnbull, Ms Credlin expressed a desire "to move on with my life and do something where I get my own voice". Sky CEO Angelo Frangopoulos confirmed Ms Credlin's appointment as a political commentator and said: "We welcome Peta to our unrivalled coverage of Election 2016."
