Barnaby Joyce has resigned as Nationals leader amid public criticism from colleagues despite insisting he was "not going anywhere" earlier in the week.
Mr Joyce announced his exit from the Turnbull cabinet at a Friday afternoon press conference in Armidale after two Nationals colleagues expressed doubts over the viability of his leadership.
"This current cacophony of issues has to be set aside," Mr Joyce said.
"On Monday morning at the party room, I will step down as the leader of the National Party and deputy leader of Australia.
"I have informed the acting Prime Minister, Mathias Cormann, of this. I informed my colleagues of this and there are a couple of things I would like to say."
