Called a "whore" and her partner labelled gay, encouraged by rock singer Elton John, handed competing petitions from more than 200,000 divided Australians, and facing bitter splits within her own ranks, Prime Minister Julia Gillard will today struggle to contain a Labor push for gay marriage.
Gillard appears likely to lose her stand against same-sex marriages in the national party conference, and could yet fail to achieve a face-saving compromise that would allow MPs a conscience vote in Parliament.
Given opposition within Labor and Gillard's wafer-thin majority, changes to the federal Marriage Act probably would not survive a conscience vote.
Supporters of gay marriages are demanding the conference votes for a new, non-negotiable policy that would drive beyond the civil unions now allowed in Queensland, Tasmania, Victoria and the Australian Capital Territory.
Queensland Premier Anna Bligh, who pushed the civil unions law through state Parliament this week, will be a powerful advocate for gay marriage today.
