A pact was signed Wednesday in Port Vila by most leading political groups, comprising around 36 MPs elected in last month's snap election.
The group has reportedly committed to forming a government when parliament sits next week, and to introducing political reform in order to stop the chronic parliamentary instability.
However, the leader of the Groan Mo Jastis Pati, Ralph Regenvanu, said one of the biggest parties, the UMP, with its long-time leader Serge Vohor in jail for bribery, has not yet fully committed to the bloc.
