Trevor Mallard is again facing pressure to stand down.
The Speaker sparked a testy debate with National MPs last night, after he said under Parliamentary Privilege a worker had committed sexual assault.
Mallard has previously apologised to the worker for wrongly accusing him of rape.
Leader of the House, Chris Hipkins, says the debate didn't reflect well on Parliament or the people involved, and Jacinda Ardern will release a statement on the matter today.
National leader Judith Collins told Chris Lynch the Prime Minister needs to be decisive.
“What she should do is tell Trevor Mallard to stand down. He needs to go, he is a disgrace to parliament.”
