Nationals senator Bridget McKenzie has claimed David Littleproud will survive as Party leader as he stares down a leadership tilt from a disgruntled colleague. On Wednesday, LNP MP Colin Boyce confirmed he would challenge Mr Littleproud for the top job when Parliament resumes next week, saying the National Party was “committing political suicide by removing itself from the Coalition”. In retaliation, all 11 National Party frontbenchers – including Mr Littleproud – resigned from Ms Ley’s frontbench and the historic Liberals and Nationals alliance was branded “untenable” under Ms Ley’s leadership, splitting the Coalition. ‘Only way forward’Later, Mr Boyce doubled down on his challenge to Mr Littleproud, saying the Nationals’ future relied on the ousting of its leader. When grilled on the issue, Mr Boyce did not rule out a different challenger to take on Mr Littleproud.
