Nestor Kirchner, Argentina's former president and a current national deputy, says he'll vote in favor of a gay marriage bill.

After failing to gain sufficient support to open debate on the bill last Wednesday, Argentina's Chamber of Deputies (la Camara de Diputados) is expected to hold a special session Wednesday to debate giving gay and lesbian couples the right to marry.

Kirchner relinquished control of Argentina in 2007 when he handed the reigns of power to his wife, Christina Fernandez de Kirchner. He currently helms the powerful Front for Victory Party (Frente Para la Victoria, FPV) and represents the Buenos Aires Province in the country's lower chamber.

During the Radio 10 broadcast of the program De Vuelta, Agustin Rossi, the head of the FPV in the Chamber of Deputies, said: “Nestor Kirchner told me he's going to vote in favor [of the gay marriage bill].”

“Gay marriage is a profound subject and we must discuss it calmly and without political dispute,” he added.

As lawmakers debate whether to legalize gay marriage, gay couples continue to marry. Last week, two men married in Buenos Aires, the fifth gay couple to do since December.

Recognition of gay unions is gaining ground in Latin America. Several Argentine cities, including its largest city of Buenos Aires, have approved civil unions for gay couples. In March, a gay marriage law took effect in Mexico City, making it the first municipality in the region to approve such unions. Uruguay recognizes gay and lesbian couples with civil unions.

If approved, Argentina would become the first Latin American country to legalize gay marriage.
