Australian Prime Minister Julia Gillard has retained the leadership of the Labor party after Kevin Rudd decided against standing for a leadership vote in the ALP caucus.

Treasurer Wayne Swan remains as deputy prime minister after Simon Crean withdrew his nomination.
"Both were duly elected unopposed and unanimously by the parliamentary caucus,'' caucus returning officer Chris Hayes told reporters in Canberra in Thursday.
He said Mr Crean was addressing caucus when Mr Hayes came out to address media.
