The Solomon Islands opposition is calling on the Prime Minister to resign, after four ministers left cabinet and joined the opposition.

Four Ministers have crossed the floor, and the opposition is to ask the Governor General to recall parliament so a no-confidence motion can be debated.

The deputy opposition leader, Matthew Wale, says there's a common thread to the departing ministers' complaints.

"Mostly it is the complaint that the Prime Minister has allowed the Minister of Finance to basically manipulate Cabinet and the cabinet process for his own ends and that of his cronies in the award of contracts, and the decision on the beche de mer issue at the fisheries ministry and so forth."

Matthew Wale says if the Prime Minister has any common sense, he will resign before a no-confidence vote can be called.

One of the four ministers who have left the Solomon Islands government says the Prime Minister no longer has control of Cabinet.

The former Fisheries Minister, Bodo Dettke, says the Government is being controlled by outsiders, mainly from the logging industry.

"I don't want to really point fingers at anyone but we're all not blind, put it that way, we're all not blind. Everyone can see what's going on. At the end of the day is it the interest for the people and our country or is the interest for the logging industry."

Bodo Dettke says if a vote of no confidence is taken, he will be voting with the opposition, and he expects more ministers to cross the floor.
