[Source: Reuters]New Zealand Prime Minister Christopher Luxon is set to face National Party ​lawmakers in Wellington after he called a meeting he said was to address increased speculation about his leadership months away from a general election. Luxon, a former CEO of Air New Zealand, also told a business audience ​to “be adult” rather than look to the government for help. If ​National were ⁠to replace Luxon as leader, he would also cease to be prime minister. A governing party has not forced out a sitting New Zealand prime minister between elections ⁠since ​1997. New Zealand media have named Attorney-General, Infrastructure and ​Transport Minister Chris Bishop and Education and Immigration Minister Erica Stanford as possible successors to Luxon.
