Bishop announced she would move to the backbench and had not yet decided whether to contest the next election, which is due by May next year. That decision could have serious implications for Morrison’s government, which has a parliamentary majority of only one seat.
Morrison emerged as the surprise winner of Friday’s party-room vote to replace Turnbull after a week of political chaos in Canberra that marked the emergence of Australia’s sixth prime minister in less than 10 years.
He took over as leader of the Liberal Party, the senior partner in a Liberal-National coalition that has consistently trailed the opposition Labour party in opinion polls in recent months.
Bishop contested Friday’s vote but was eliminated in the first round, with Morrison then emerging as a surprise compromise winner over Peter Dutton, Turnbull’s conservative challenger who brought the leadership crisis to a head earlier in the week.
