TORONTO -- Ontario Progressive Conservative Leader Tim Hudak predicts a challenge to his leadership at this weekend's policy conference will be a "footnote in the history of the party."

Some Tories upset that they took only one of five byelections last month moved a motion to amend the party's constitution at their meeting in London to allow for a review of Hudak's leadership.

Hudak says there's nothing unusual about Conservative infighting, and insists the party will emerge from their meeting united and ready to fight an election.

Supporters say now is not the time to be talking about reviewing Hudak's leadership, especially with Premier Kathleen Wynne threatening an election if the minority Liberals can't get bills passed in the legislature.

Hudak captured 78 per cent support in the leadership review that was automatic after the Tories lost the 2011 election, and says he doesn't need to face another one.

Two Conservative caucus members, both failed leadership contenders, said publicly that Hudak should allow the motion to be debated this weekend.

Randy Hillier has been removed as PC labour critic while Frank Klees has declared his support for the leader.
