The vote will be the only business of the special session at 10am.
Newton Savi, the President of East Sepik Tertiary Students Union made this call in Wewak yesterday.
He said the six open MPs must join Governor Sir Michael Somare in the Opposition side to remove the Prime Minister of Peter O'Neill who he claimed was destroying the country's economy and not respecting the rule of law.
Savi told Loop PNG that, if the Opposition are successful in the VONC, Sir Michael is good candidate to lead a unity government with 12 months left for the next national elections.
"This will really show that Don Polye, Sam Basil and Belden Namah are truly sorry for what they did to Sir Michael during the political impasse," Savi said.
