Former Labor political candidate Nicole Cornes has successfully sued Channel Ten after alleging comedian Mick Molloy defamed her on its Before the Game football show.

Molloy allegedly questioned the fidelity of Ms Cornes, who is married to former AFL coach Graham Cornes, joking she had slept with former AFL player Stuart Dew.

Ms Cornes took her complaint to the South Australian Supreme Court where her lawyer Stuart Littlemore, QC, said the remarks were not a trivial jest.

He said it was hard to imagine what worse defamation could be broadcast to impugn a women's "self-respect and dignity".
