In Parliament last week, while the Prime Minister was speaking, a National Party MP hurled a "very sexist remark" across the Chamber.

He - and yes, Newshub can confirm the remark was made by a man - called Prime Minister Jacinda Ardern a "stupid little girl."

As soon as the comment was made, Speaker Trevor Mallard stopped proceedings in the House, calling for the person who made the "very sexist remark" to apologise.
