National Party of Australia
In September 2008, Joyce replaced CLP Senator and Nationals deputy leader Nigel Scullion as leader of the Nationals in the Senate, and stated that his party in the upper house would no longer necessarily vote with their Liberal counterparts in the upper house, which opened up another possible avenue for the Rudd Labor Government to get legislation through. Joyce was elected leader in a party-room ballot on 11 February 2016, following the retirement of former leader and Deputy Prime Minister Warren Truss. Joyce was one of five politicians disqualified from parliament in October 2017 for holding dual citizenship, along with former deputy leader, Fiona Nash.
