Minister for Women Nicola Grigg says she is "absolutely" backing Christopher Luxon, and does not believe Erica Stanford can be prime minister.
"She's a good friend of mine, but she's not a prime minister," Grigg told Stuff, after landing in Wellington.
She said Chris Penk, rumoured to be Stanford's "numbers man", had never called her to get support for a leadership change.
She reiterated that Stanford was not prime minister material
"I don't believe she's a prime minister. She's a good friend of mine, but I don't believe she's a prime minister," Grigg said.
