New Deputy Prime Minister Michael McCormack is set to decide who will be his replacement as veterans affairs minister within days.
The new Nationals leader has taken on the infrastructure and transport portfolios, and will decide in the next couple of days who will become the nation's third veterans affairs minister since December.
Party members and senators gathered for a special party meeting on Monday to see former leader Barnaby Joyce formally stand down after weeks of fall out surrounding his marriage break-up and relationship with a former staffer who is now pregnant.
Mr Joyce, who's now on the back bench in parliament, spoke to reporters in Canberra.
