A South Australian Labor frontbencher has apologised to federal Finance Minister Penny Wong after saying the child she is having with her same-sex partner, is not hers.

Wong and her partner Sophie Allouache are expecting their first child in Dece

mber.

Labor MP Tom Kenyon today made the remarks when discussing his opposition to same-sex marriage because a man and a woman can biologically produce.

“Gay people can’t have kids together,” Kenyon told the ABC.

When an ABC reporter remarked Wong was expecting a baby with her partner later this year Kenyon responded saying, “But she’s a lesbian couple, that’s through IVF.”

“I don’t want to be rude to Penny but it’s not her baby, if you know what I mean, it’s not biologically, it’s not the biological product of two people.”

Kenyon later issued a statement saying he didn’t mean to offend the couple, but said he still opposes same-sex marriage and will be voting against it at Labor’s December national conference.

“I apologise if those comments offended them in any way,” Kenyon said.

“I don’t think it’s discrimination to say to people a man and a woman getting together, having kids, bringing up a family, that’s special, that’s important, that’s marriage.

“In general a gay couple cannot produce children that’s almost absolute, a gay couple cannot produce children and most married couples do.”

Kenyon’s views put him at odds with outgoing Labor Premier Mike Rann, Liberal Opposition Leader Isobel Redmond and incoming Labor Premier Jay Weatherill who have all spoken out in favour of changing the Marriage Act to allow same-sex couples to marry.

Last month incoming Labor MP Gerry Kandelaars used his maiden speech to call for marriage equality and changes to the state’s IVF laws to allow lesbian access.

A same-sex marriage private member’s bill – sponsored by SA Labor MP Ian Hunter and Greens MP Tammy Franks – is currently before the South Australian Parliament.
