Queensland's education minister says he has no interest in leading his party again should Premier Campbell Newman lose his seat.

John-Paul Langbroek says he's confident Mr Newman will retain his Ashgrove seat at the next election.

Political commentators have said the LNP is likely to retain government but Mr Newman will lose his seat, leaving the party to scramble for a new leader.

Mr Langbroek, who was opposition leader from 2009-11, says Mr Newman is the best person to lead the party, and he wouldn't comment on speculation that Treasurer Tim Nicholls and Transport Minister Scott Emerson are considered likely successors.
