"There are certain people who are still trying to create instability and portray divisions between the prime minister and his deputy and our major coalition partners," O'Neill said over the weekend, according to The National.
"This will not work because we have all agreed, including the deputy prime minister, that the election will go ahead as scheduled."
Deputy Prime Minister Belden Namah has been advocating an election deferral for months, and the Post-Courier, recently reported about a plot among political powerbrokers to oust O'Neill ahead of the election.
O'Neill would even prefer to delay the election but admitted to The National that he could not make such decision.
"If the law had allowed me to, I will defer the election," he reportedly said.
"But nowhere in the Constitution does the law allow the prime minister to defer the election."
Election campaigning is effectively underway and the writs are expected to be issued on Friday.
