Jacinda Ardern’s Labour party has committed to banning gay conversion therapy if re-elected in New Zealand’s 17 October election. In an interview with Express magazine, the 40-year-old Labour leader said she was moved to oppose the practice after watching a Joseph Gordon-Levitt movie. “I still remember watching the film Latter Days at the film festival in Wellington some years ago. That film never left me,” she said. “It’s one of the reasons I feel quite strongly about this policy.” The 2003 movie depicts a secret relationship between a closeted Mormon and an openly gay friend. Ms Ardern was raised a Mormon but left the church in her 20s in solidarity with gay friends.
