Barnaby Joyce will return to the nation's second-highest office, marking a political comeback three years after losing the deputy prime ministership to scandal. Queensland Senator Matt Canavan moved a spill motion to bring on the leadership vote at a partyroom meeting this morning. Sources have told the ABC Mr Joyce defeated Deputy Prime Minister Michael McCormack in a very close contest this morning after years of seeking a return to his party's leadership. Mr Joyce resigned as leader and deputy prime minister in 2018 after facing sustained pressure. He was accused of sexual harassment — a claim he strenuously denied. Speaking before the vote, Nationals MP Dr Anne Webster said she thought some female voters would not support Mr Joyce replacing Mr McCormack. "I've had people write to me about this of course and some would be very unimpressed," she said. "They are issues for Barnaby Joyce should a change occur, that would be for him to sort through."
