Germaine Greer has described a petition to ban her from speaking at a university event as a "put-up job".

The Australian feminist author is scheduled to appear at Cardiff University for a public lecture, Women & Power: The Lessons of the 20th Century.

But the university's Students' Union women's officer Rachael Melhuish has launched an online petition urging the institution to cancel the event, citing Ms Greer's views on transgender people.

"Greer has demonstrated time and time again her misogynistic views towards trans women, including continually misgendering trans women and denying the existence of transphobia altogether," Ms Melhuish says in the petition.
