Bolger was ousted in 1997 and replaced as National leader and prime minister by Jenny Shipley. The National/New Zealand First coalition dissolved in 1998, and the consequent cobbling together of another coalition between National and the deserters of various parties contributed to the government's defeat in 1999.
Jenny Shipley took over as National leader and prime minister in 1997 after Bolger was ousted. The National/New Zealand First alliance fell apart in 1998, leading to a hasty assembly of another coalition between National and defectors from other parties, which ultimately led to the government's downfall in 1999.
