Former Australian prime minister Kevin Rudd ruled out a challenge to incumbent Julia Gillard in a vote for the leadership of the Labor Party.
Julia Gillard will remain as Prime Minister after she stood unopposed in a leadership ballot.
Rudd, who was rolled by Gillard in 2010, said he gave his word a year ago that he would not challenge again, and that he would only return to the leadership if drafted with the overwhelming support of the Labor Party. But he said those circumstances did not exist at present.
Unwed mothers were pressured, deceived and threatened into giving up their babies from World War II until the early 1970s so they could be adopted by married couples, which was perceived to be in the children's best interests, the senate committee report found.
Western Australia was the first of five state and territory governments to apologise for forced adoption. Australia has eight such governments.
Roman Catholic hospitals in Australia apologised in 2011 for forcing unmarried mothers to give up babies for adoption and urged state governments to accept financial responsibility.
PM apologises to Australian mothers for 'forced adoptions'
The Australian Prime Minister Julia Gillard has delivered an historic national apology to the thousands of unmarried mothers, who were forced by government policies to give up their babies for adoption over several decades.
The Australian Prime Minister Julia Gillard lights a beacon in celebration of the Queen's Diamond Jubilee.
She said: "These beacons glowing around the world symbolise one family across a wide world, the family of the Commonwealth nations, rich in their diversity but united now in admiration for the unstinting service of the Queen."
