If Sabah Progressive Party (Sapp) had its way, it would be the first time in the nation's history that a vote of no-confidence is to be moved against a prime minister.
"In the coming sitting of the Parliament session starting Monday, June 23, our MPs will support a vote of no confidence on the PM.
"Whether the motion will be tabled by our party MP or another MP will be decided in due course," said party boss Yong Teck Lee.
Sapp has two parliamentarians - Dr Chua Soon Bui (Tawau) and Eric Enchin Majimbun (Sepanggar).
Will Sapp make history or will its threat fizzle out? Malaysiakini has the following reports on the issue.
