2018 Darling Range state by-election

A by-election for the Western Australian Legislative Assembly seat of Darling Range was held on 23 June 2018 following the resignation of Barry Urban on 8 May.

Won by Labor for the first time in the seat's history at the landslide 2017 state election, the Liberals regained the seat.

Background
Following a large 19 percent two-party swing, Barry Urban was the first ever Labor candidate to be elected to the previously safe Liberal seat of Darling Range in the seat's 64 year history at the landslide state election in March 2017. In November 2017, Urban resigned from Labor and moved to the crossbench to sit as an independent, after questions were raised about his academic claims and his wearing an overseas police service medal he had not been awarded. Urban was referred to the procedures and privileges committee, which in May 2018 recommended his expulsion from the Legislative Assembly for contempt of parliament and misleading the House. Urban resigned immediately after the committee's report was released.

Labor originally selected Colleen Yates as its candidate for the by-election. However, on 24 May 2018, Yates announced that she would withdraw from the race, after reporters discovered that she had incorrectly claimed multiple university degrees which she had never obtained on her LinkedIn profile.

Results
Ninety-two minutes after polling booths closed, the Australian Broadcasting Corporation's Antony Green called the by-election for the Liberals.
