Judith Collins is no longer leader of the National Party.
On Twitter, she realised the following statement:
"I am pleased to say that I am just the MP for Papakura again. It’s been a privilege to take over the leadership of the National Party during the worst of times and to do so for 16 months. It has taken huge stamina and resolve, & has been particularly difficult because of a variety of factors.
"I knew when I was confided in by a female colleague regarding her allegation of serious misconduct against a senior colleague, that I would likely lose the leadership by taking the matter so seriously. If I hadn’t, then I felt that I wouldn’t deserve the role.
"I didn’t ask for the allegation to be given to me. I am proud of the support I received from Dr Shane Reti, a man of principle, and I will continue to advocate, not only for Papakura, but for those who have no voice.
"A big thank you to the wonderful staff in the National Leader’s Office, my Papakura Office, National Party members & my wonderful colleagues. I’m so pleased that I can spend more time with my family & friends & I will not miss the gruelling media schedule."
It's understood Dr Shane Reti will be the interim leader, with a decision on the full-time replacement to be made next week.
Simon Bridges earlier accused Collins of trying to hold onto the National Party leadership at any cost, describing her demotion of him on Wednesday as "truly desperate stuff".
