Peters' negotiators went back to Labour and made it clear one thing would beat that, Prime Minister for some of the time.
It was instantly rejected by Labour. Peters himself did not make the request of Labour. One of his negotiators did.
RNZ's Kathryn Ryan alluded to the issue on Nine to Noon yesterday. She was in the Press Gallery in 2005 when the issue last arose. Some of Peters' backbenchers - there were 13 MPs then - had been having subterranean talks with National backbenchers about giving Peters a stint at being Prime Minister. I wrote about it in May 2005 after getting it confirmed from three NZ First sources and two National sources.
Peters at the time wasn't exactly furious but said if any of his MPs had a mind to their list ranking they would not be discussing it.
As the election got closer and his party's poll ratings started to slide, he became grumpier and grumpier and blamed his fall in support on the story.
Nothing like power-sharing actually eventuated; Peters became Labour's foreign minister and his party supported Labour for its third term.
Herald correspondent John Armstrong raised the power-sharing issue at the weekend in his political column following Key's decision last week to lift his ban on working with NZ First post-election.
In light of John's column, I asked the Prime Minister this morning if he would rule out a power-sharing deal and he said "that's not on the table."
Pressed further, he said ''No, Winston Peters won't become Prime Minister."
ZB's Barry Soper asked him if it were put on the table, would he consider it, and Key said No.
CLARK OUT OF THE BLOCKS
Until now, former Prime Minister Helen Clark has been extremely guarded in her comments about wanting the top job at the United Nations.
But in an interview with The Guardian, one of her favourite papers, she contemplates the possibility: "If there's enough support for the style of leadership that I have, it will be interesting."
The successor for Ban Ki Moon will need to be found next year so it's not surprising Clark is more willing to discuss it.
