Labour MP Trevor Mallard should "get on top of his anger issues" Prime Minister John Key said today.
Mr Key made the statement when asked about yesterday's incident in Parliament, which ended up with Mr Mallard being ordered out of the debating chamber.
Speaker Lockwood Smith ruled that Mr Mallard had insinuated the prime minister was a liar by calling out "your nose is growing, your nose is growing" while Mr Key was speaking.
It is an offence to call anyone a liar in Parliament.
Mr Mallard hotly disputed actually using the word and shouted "for goodness sake...that's the worst decision you've ever made", as he left the chamber.
The MP wrote on a blog last night that he was looking at moving a vote of no confidence in the Speaker, which would be a very serious move.
Mr Key said Mr Mallard could have chosen a simple course of action.
"That was to withdraw and apologise and make his own point," Mr Key said.
"Instead he blew a foo foo valve. Trevor needs to get on top of his anger issues."
Mr Mallard did not move a vote of no confidence in Dr Smith when Parliament sat today.
In a long career as an MP, Mr Mallard has a history of letting his temper get the better of him.
He got involved in a fight with National MP Tau Henare, which resulted in a court order that he attend an anger management programme.
Former prime minister Helen Clark once demoted him from the front bench, jokingly saying she would like to "Taser" him.
In his role as the Government's "bovver boy" he taunted National leader Don Brash about his affair.
As sports minister he once vowed to take revenge against International Rugby Board (IRB) chairman Vernon Pugh and Australian Rugby Union boss John O'Neill.
He said his preferred remedy would "involve Heinekens in particularly uncomfortable places".
