A spokesperson for the opposition says it has not initiated any defections, amid reports that a dozen Solomon Island MPs have decided to quit the government side.
The Solomon Star says eight ministers are resigning after losing confidence in the prime minister, Manasseh Sogavare, and are expected to deliver their letters of resignation to Government House today.
It also says four backbenchers have decided to quit and it's expected that a no confidence motion will be lodged today.
Douglas Marau, the press secretary for Leader of the Opposition, says there have been discussions with disgruntled members of the government but wouldn't comment further.
He says any issues the government coalition is having are internal and of their own making.
On Sunday, the deputy prime minister, Douglas Ete, resigned reportedly after he learned about plans to remove him.
