National's Shadow leader of the House Chris Bishop authorised a social media video which made fun of a speech made by new Labour MP Anna Lorck. Bishop has now been referred to the privileges committee by Speaker Trevor Mallard. The National MP will have to explain himself to the privileges committee – a group which acts as Parliament's rule keepers and can dish out punishments.
