The Solomon Islands opposition says the government must seek outside help to restore law and order.
The opposition's spokesman on foreign affairs, Alfred Sasako, says links between some politicians, police and gunmen move the country into a mobster-style administration.
Mr Sasako says the prime minister must ask for help with policing from Commonwealth countries.
"The whole issue now lies with Australia and New Zealand talking to the prime minister that they fully support him but his own people can not do the work for him. It is time to accept that it is time for an external intervention."
Mr Sasako says without law and order there will be no investment and no economic recovery.
