The two main political parties in Vanuatu are vying for members of parliament to cross the floor to get the numbers needed before a vote this Friday to establish who has the majority.
The People's Progressive Party leader Sato Kilman was reinstated as Prime Minister last Friday following an Appeal Court decision that determined a motion to topple him last month was unconstitutional.
But a special parliamentary session has been called for this Friday to establish whether he or Serge Vohor, the leader of the UMP party, have the absolute majority.
The first political advisor to the Prime Minister, John Shing, says they're confident that Mr Kilman will get the numbers.
"There has been an indication that some would be willing to move across, of course there is a lot of lobbying going on on both sides of the camp, both the opposition and the government are both lobbying hard for members of both sides to cross the floor."
One MP has already swapped sides - Steven Kalsakau has joined the PPP but Mr Kilman needs two more to get his majority.
