The new Solomon Islands opposition grouping says it still has the numbers in Parliament to remove the Prime Minister Manasseh Sogavare.
This is despite Mr Sogavare regaining the support of three of the 12 MPs who resigned from his government at the weekend by offering them ministries.
Nine Cabinet Ministers and three backbenchers defected to a new Opposition grouping and called on the Prime Minister to go, or face a vote of no confidence in parliament.
The former Finance Minister Gordon Darcy Lilo, who was among the primary defectors, says they are seeking legal advise on the Governor General's refusal to reconvene parliament.
But Mr Lilo says the Prime Minister's support was itself losing further ground in the ongoing lobbying among MPs.
"They will go their own way to try and discredit the movement that's going on right now, but the bottom line for this country right now is there must be a change of leadership, there must be a change of leadership."
