MLAs crossed the floor to join the Nationals. The Nationals then governed in their own right until 1989. The Coalition was renewed in 1991, and won power under Rob Borbidge from 1996 to 1998. The Queensland Liberals and Nationals had contested separately for the Senate in federal elections until the 2007 election, when they ran a join Senate ticket for the first time in 30 years. In 2008, the two parties agreed to merge, forming the Liberal National Party (LNP), under the leadership of former National Lawrence Springborg. Although it is dominated by former Nationals, it has full voting rights within the Liberal Party and observer status within the National Party. Springborg stood down in 2009, and was succeeded by former Liberal John-Paul Langbroek. The LNP won an overwhelming majority government in the 2012 state election under the leadership of former Liberal Campbell Newman, who had taken over from Langbroek a year earlier. However, it lost power in 2015, and Springborg returned to the leadership, only to lose a challenge by former Liberal Tim Nicholls in May 2016. Following another loss in the 2017 election, Nicholls stood down as LNP party leader and was succeeded by Deb Frecklington, who holds the ancestrally National seat of Nanango, Bjelke-Petersen's old seat. At the federal level, 15 LNP MPs sit with the Liberals, including federal Liberal leader Peter Dutton; six sit with the Nationals, including federal Nationals leader David Littleproud. LNP Senator Matt Canavan sits with the Nationals, while the LNP's four other senators sit with the Liberals. The highest-profile LNP MP in recent years has been former federal Nationals leader and Deputy Prime Minister Warren Truss. The LNP has an informal agreement with its federal counterparts as to which party room in which LNP members will sit. Incumbent MPs retain their previous federal affiliations, whereas members who win seats from the ALP that previously belonged to the Coalition will sit with the previous member's party. An amicable division of seats was decided upon for new seats or seats that have never been won by the Coalition. In practice, all LNP MPs from Brisbane and most LNP MPs from the Gold Coast and the Sunshine Coast sit with the Liberals, while those from rural seats usually sit with the Nationals.
