Kevin Rudd has finally confirmed he will take on Julia Gillard at a party room leadership vote on Monday as he tries to make a comeback as prime minister.
Mr Rudd said the Labor party was "heading for the rocks at the next election''.
"That's why I'm here today because I believe that to do the best for Australia and Labor things have to change,'' he said in Brisbane on Friday.
"It is no secret that our government has a lot of work to do if it is to regain the confidence of the Australian people.
"Rightly or wrongly Julia has lost the trust of the Australian people and starting on Monday I want to start restoring that trust.
