THE Labor Party’s two most prominent gay politicians – one from the Right and one from the Left – will spearhead the push for marriage equality, as Julia Gillard struggles to maintain her authority on the issue.

ACT Deputy Chief Minister Andrew Barr, from the Right, will move and federal Finance Minister Penny Wong, from the Left, will second a ”Rainbow Labor” motion at this weekend’s ALP conference declaring that Labor ”will amend the Marriage Act to ensure equal access to marriage under statute for all couples irrespective of sex”.
