The government’s bid to legislate this year to protect LGBTI students from discrimination at religious schools has failed because of an impasse over the detail. After weeks of negotiation and tactical maneuvering between the government and Labor, Scott Morrison on Wednesday produced his own bill and suggested both sides give their parliamentarians a conscience vote. “It’s disappointing that we have been unable to reach agreement between the parties, but I’m prepared to give it one more go,” he said.
