Denis Napthine has quit as leader of the Liberal party after leading his government to a loss in Saturday's Victorian election.

At the end of his concession speech, Dr Napthine announced he would call a meeting of the Liberal party where he would stand down as leader.

"I can say that it is time for me to step down as leader," he said.

"I believe the party has plenty of opportunity to choose a new leader for a new future so that the Liberal Party will continue to be a strong, dynamic political force here in Victoria."

Michael O'Brien and Matthew Guy are the two most likely contenders to succeed Dr Napthine.

"Those two have been excellent ministers, both as Treasurer and as Planning Minister," Liberal MP Mary Wooldridge told the ABC.
