In May 2022, senior Australian Labor Party MP Tanya Plibersek compared former defence minister Peter Dutton from the Liberal Party of Australia to Voldemort. During a discussion about Dutton's prospects of becoming Liberal Party leader on Brisbane radio station 4BC, she said: "I think there will be a lot of children who have watched a lot of Harry Potter films who will be very frightened of what they are seeing on TV at night, that's for sure... I am saying he looks a bit like Voldemort and we will see whether he can do what he promised he would do when he was last running for leader which is smile more." A spokesperson from Plibersek's office said that she had reached out to Dutton soon after the interview to offer an unreserved apology and to say that she should have not made the remark. Labor Party leader, prime minister Anthony Albanese said Pilbersek's comments were "not acceptable" and that she had done the right thing in offering an apology. Dutton confirmed Plibersek had apologised. In response, Dutton said that while the comments were unfortunate, they were "water off a duck's back." He said that he realised that he was "not the prettiest bloke on the block" and said that he was bald due to being diagnosed with a skin condition.
