Vanuatu's opposition has lodged a motion of no-confidence in the government, set be debated next Thursday.
The Opposition spokesman Kal Moli says the opposition leader Serge Vohor is exercising his constitutional duty to support calls for Vanuatu to have a stronger leadership.
Prime Minister Ham Lini claims to have a majority of 34, while the opposition's power base has swelled to 18 after the recent ousting of the Greens Confederation from the coalition government.
But while Mr Moli says it's too early to disclose names, they've reached agreements with a number of members of the government to defect and vote with them.
The speaker of parliament, San Dan Avock, has confirmed he received the notice for the motion yesterday.
"Yes, I can confirm, the motion is still with me now. I'm signing the notice to notify the members of parliament of the motion that I have recieved. The motion is in order for debate on Thursday next week."
Meanwhile, the Daily Post reports that government insiders strongly insist the government still has the support of its 34 MPs.
