Speech by Prime Minister John Key on Pike River Mine tragedy:
This afternoon New Zealand has been devastated by the news we have all been dreading.
A second explosion at the Pike River Mine confirms our very worst fears.
The 29 men whose names and faces we have all come to know, will never walk amongst us again.
This is a national tragedy.
A tragedy for the men's families, their workmates and friends, their community and our nation.
New Zealand is a small country.
A country where we are our all our brothers keeper.
