The Vanuatu Daily Post reported the defection of MPs Ephraim Kalsakau and Fred Tasso of the Workers Party for Vanuatu Development brings the opposition numbers up to 10.
Speaking to the paper about the move Mr Tasso claimed Prime Minister Charlot Salwai failed to honour a promise to grant the party a parliamentary secretary position in the Labour department.
He said they also did not want to be part of any attempt to increase MP salaries, while the ordinary citizens of the country struggled to make ends meet.
