A 40-year-old woman is due to appear in court today, charged with aggravated stalking of Western Australian Greens senator Jordon Steele-John.
Police will allege the Perth woman was a former partner of Senator Steele-John.
Detectives from the WA Police Family Violence Investigation Squad said they charged the Perth woman with one count each of "aggravated stalking with intent to intimidate" and "demanding property by written threats".
The woman will appear before the Perth Magistrates Court today.
Senator Steele-John took leave from the parliament in October after a group of current and former party staffers wrote to Greens leader David Shoebridge about "multiple allegations of serious misconduct" by Senator Steele-John relating to "his behaviour in the presence of women" .
Senator Steele-John has denied the allegations, including in a lengthy and since-deleted letter posted to social media.
An independent inquiry into the allegations has been commissioned by the WA branch of the Greens.
Senator Shoebridge has previously said leave was appropriate in the circumstances and he would not prejudge the inquiry.
