The Prime Minister has hit out at Labour MPs grilling him about the Pike River families' campaign to re-enter the sealed mine.
John Key says the Government will write to Bernie Monk and the other families, explaining why it doesn't support their plan to enter the drift and recover the bodies of the 29 men who died there.
Labour's Damien O'Connor pressed Mr Key to reveal his reasons, which prompted an outburst from Mr Key.
“All of the advice we have received is that it is a very very substantial risk. The member’s actually doing what’s right for the health of people. If that member wants to kill people going in the mine, he should carry on that way.”
The outburst was met with calls of “order” from the Speaker.
Mr Key told Parliament he would "sleep very peacefully tonight" with the commitments he made.
