The People's Justice Party was to decide yesterday whether to accept 37-year-old Elizabeth Wong's resignation in the central Selangor state assembly.
News reports said the photos were believed to have been taken by her ex-boyfriend without her knowledge.
She said it was "an insidious and underhanded attempt" to smear her reputation, adding that "the real objective is to discredit the party".
"I have done nothing wrong. I wish to state that I am not ashamed of my sexuality as a woman and as a single person. I have broken no law," she said, her eyes brimming with tears.
"In the interest of my party I have decided to offer my resignation," said Ms Wong.
