Former deputy prime minister Winston Peters has attacked a new book on the National Party's recent turmoil, saying it is factually inaccurate.
The book suggests that it was the decision of Labour leader Jacinda Ardern to offer Peters the role of deputy prime minister at the eleventh hour that clinched coalition negotiations in 2017.
Peters issued a statement attacking Blue Blood and its author, Andrea Vance and saying that the role of deputy prime minister was decided early in negotiations.
"The comical absurdity of Vance's 'work' in suggesting that Jacinda Ardern offered me the deputy prime ministership in the 11th hour of negotiations to clinch the deal is something not one National Party MP believes. Why?
"Because they have a record of day one in negotiations as we do, and as Labour does, in their case. The deputy prime ministership was decided on day one of negotiations, as it was in 1996, or in terms of foreign affairs, on day one of the 2002 negotiations with Helen Clark and her team," Peters said.
