Bill Shorten has been elected Labor leader.
He defeated former deputy prime minister Anthony Albanese in a caucus and rank-and-file vote announced this afternoon 55-31.
Members, however, preferred Mr Albanese, giving him 59.92 per cent of the rank-and-file vote.
Mr Shorten, 46, of the right faction, is the first Labor leader to be elected under rules introduced by former prime minister Kevin Rudd.
He is the former Australian Workers Union national secretary, a former Workplace Relations Minister and is married to Chloe Shorten, daughter of Governer-General Quentin Bryce.
The announcement was first made via Labor's Twitter account.
