House Speaker Trevor Mallard receives influx of complaints about MPs' behaviour

The public is fed up with Parliamentarians' performance and the complaint line is ringing hot with Speaker Trevor Mallard receiving an influx of messages about MPs' misbehaviour.

And it just so happens that Wednesday was a perfect display of the descending decorum in our highest House, with MPs cackling away after Jacinda Ardern and Judith Collins hauled 'Karens' into the hate speech debate.

'Karens' being the pejorative Millennial slang for entitled white women.

"I also, as it happens, disagree with the Member's statement on Twitter that somehow it will become illegal to call someone a 'Karen'," the Prime Minister said. 

"That is absolutely incorrect, and I apologise that means these laws will not protect the member from such a claim."

After a leaky week, the National Party were turned on by one of their old mates, with former National MP Chris Finlayson savaging them to reporters. 

"Declaring a state of emergency for the National Party is probably not before time, but Mr Finlayson made his reasons starkly clear," Deputy Prime Minister Grant Robertson said during the general debate. 

"It's Finlyason's empathy that I've really missed around here, quote: 'You're talking to the wrong person if you expect me to express any sympathy for the current plight of the National Party... they deserve everything that's come to them'."

The Deputy Prime Minister essentially turned the general debate into the Robertson Roast hour, a retelling of the late-night caucus meeting that led to Todd Muller's resignation. 

"The night of the short plastic knives," Robertson dubbed it. 

Not a National MP was spared.

"Andrew Bayly was pulling his slippers on and putting on his Versace night robe," Robertson said, going on to describe Barbara Kuriger as the "snitch in chief", and taking a crack at Chris Bishop. 

"Todd Muller's numbers man and a well-known shiver looking for a spine to run down."

And Robertson did not forget the leader - or the previous leader. 

"It's clear to me the greatest threat to free speech in New Zealand is the leader of the Opposition. She has told her caucus not to talk to the media so Simon Bridges hit Instagram about how he was going to keep talking to the media.

"Free Simon Bridges!"

Parliament's oldest MP Ian McKelvie is sick of the child's play.

He asked the Speaker to "report back to us tomorrow on whether you think the debate has been constructive in any way". 

Mallard agreed it hadn't been and revealed that voters have had enough too. 

"Yesterday and on Wednesday last week, significantly more public reaction to misbehaviour in the House than I've had for some time."

Sure, a laugh once in a while is fine, but Parliament costs more than $20,000 an hour to run, which seems a bit steep for a LOL.
