The Vanuatu Republican Party, or VRP, has denied reports of a split within its group of 8 MPs.
The denial comes as lobbying continues between political parties over the formation of the new government, following the general election two weeks ago.
The Daily Post newspaper reports the VRP President Maxime Carlot Korman says his party is united and that he is on course to become Vanuatu's next Prime Minister.
Mr Korman says he has reached agreements with the Union for Moderates Party, Greens and People's Progress Party as well as several independent MPs to form a bloc.
He says this would give him the support of 30 MPs in the 52-seat parliament.
Mr Korman has dismissed a Daily Post report from last week that up to four VRP MPs had agreed to join the rival bloc, formed around the Vanua'aku Pati and National United Party, which also claims the support of a majority of MPs.
