Two Labour MPs were kicked out of Parliament's debating chamber this afternoon in a heated exchange over rules of the House.
Speaker David Carter ejected both Trevor Mallard and Chris Hipkins.
The Labour MPs became the first to be booted out of Parliament under the new Speaker after they tested Carter's patience during question time.
Opposition MPs were attempting to raise a point of order during questions on the Prime Minister's relationship with the GCSB.
Mallard challenged the Speaker over why he didn't rule against the Prime Minister for repeatedly making comments which were out of order.
"I want to know if it's going to be even both ways," Mallard said.
The senior Labour MP then challenged Carter to listen to the points of order and when Carter intervened Mallard asked the Speaker "to sit down till I'm finished" at which point he was ordered to leave the chamber.
Hipkins then attempted to raise Mallard's point of order and Carter determined that it was a relitigation of the matters and Hipkins was also asked to leave.
ONE News reporter Simon Bradwell tweeted that today's events have been a long time coming and the Opposition and Speaker have been on collision course from day one.
