The Premier Colin Barnett has dismissed calls by Liberal MP Rob Johnson for him to resign.
Mr Johnson has been an outspoken critic of the Premier ever since he was dumped from Cabinet in the lead up to the last election.
He has told the ABC's 7.30 program, it is time for Mr Barnett to go.
"I think the latest Newspoll shows that he's not exactly flavour of the month and he may becoming a liability to the Liberal Party," he said.
"It is time for a change, or a re-allocation as I think he likes to put it."
Mr Johnson said he got over being dumped from cabinet a long time ago.
The Premier says a decision about when Western Australians will go back to the polls in the wake of the bungled WA Senate election will be made soon.
