In the Sydney Morning Herald:

Prime Minister Julia Gillard will continue to oppose gay marriage in Australia despite US President Barack Obama publicly endorsing it in a national television interview overnight.

Ms Gillard today said she stood by her beliefs and would not vote for a private member's bill set to be introduced in Federal Parliament later this year to allow same-sex couples to marry.

"I know President Obama has made that statement," Ms Gillard told ABC radio station 774 today.

"I haven't had the opportunity to view it myself. I've seen the reports of it, but no, my view hasn't changed and when a bill comes to the parliament later this year ... I won't vote for it."

Asked if her progressive credentials were not measuring up, Ms Gillard replied: "Well you know, I believe what I believe ... You can judge it."
