Premier Barry O'Farrell has dismissed calls for him to suspend three of his MPs over an alleged corruption scandal, saying until the corruption watchdog made a statement on its activities the matter was "pure speculation".
The Independent Commission Against Corruption raided the offices of central coast Liberal MPs Chris Spence and Darren Webber on Friday, seizing computers and documents.
The raids are believed to be linked to allegations, revealed by Fairfax Media last year, that two staff members of NSW energy minister Chris Hartcher, another central coast MP, funnelled political donations through a front company before the 2011 state election.
Opposition Leader John Robertson has called for Mr O'Farrell to suspend Mr Spence, the member for The Entrance, and Mr Webber, the member for Wyong, while Greens MP John Kaye said Mr Hartcher should be stood down until ICAC resolved the matter.
But on Sunday Mr O'Farrell warned against jumping to conclusions in the absence of any statement from ICAC.
"Until the Independent Commission Against Corruption makes a statement about what may or may not have occurred, until it says what those activities were about, it's very hard for anybody to either to speculate or indeed for a party leader to make a decision about the future of any MP," Mr O'Farrell told radio 2UE.
"Until the Independent Commission Against Corruption explains what it may or may not be doing, everything else is just pure speculation, including the over-the-top statements from the Greens and the Labor party.
"The disadvantage for everybody here is this is speculation building on speculation. In the absence of a statement by the Independent Commission Against Corruption, no one knows the facts."
Mr O'Farrell said the Liberal Party had referred issues surrounding donations to the central coast Liberal campaign to the Electoral Funding Authority. However, there had been no statements from ICAC that it was investigating the matter.
He added that there was "no speculation at this stage of any ICAC activity in relation to the offices of Mr Hartcher".
The commission does not comment on any matter that is under ongoing investigation or consideration. On Sunday ICAC neither confirmed nor denied the existence of any investigation. A spokeswoman said no statement would be issued.
"Mr O'Farrell should suspend both the Member for Wyong and the Member for The Entrance from the Liberal Party pending the outcome of these extremely serious ICAC investigations," Mr Robertson said on Sunday.
