Australian PM surprises with Sept election call

CANBERRA, Jan 30 (Reuters) - Australian Prime Minister Julia Gillard stunned voters on Wednesday by calling an election for Sept. 14, eight months away, in her first major political speech for 2013.

Gillard's minority holds a one seat majority with support from a group of independents and the Greens, and polls suggest her government would be swept from office if elections were held now.

Australian election campaigns usually last just over a month, and 2013 is an election year, but Gillard's announcement means the rest of the year will effectively be one of the longest campaigns in Australian political history.
