NSW Opposition Leader Chris Minns says he doesn’t think NSW Premier Dominic Perrottet revealing he wore a Nazi costume to his 21st birthday party will have a “big impact” on the New South Wales election.

“There are many other issues to speak about and debate as we get closer to polling day,” Mr Minns said in a media conference on Saturday.

“Whether it is the cost-of-living crisis or whether it is getting youth more engaged in sport and off the couches.”
