Independent Oliver Yates to challenge Liberals' Chinese election signs

Exclusive: candidate who contested John Frydenberg in Kooyong says material was 'clearly designed to deceive voters'

Independent candidate Oliver Yates has confirmed he will challenge Liberal party Chinese language signs, designed to resemble Australian Electoral Commission material, in the court of disputed returns.

Yates - who unsuccessfully contested the seat of Kooyong against treasurer Josh Frydenberg - told Guardian Australia he will lodge a challenge before the 40-day deadline after the return of writs, set to expire on 31 July.
