TORONTO - Divisions within Ontario's Progressive Conservative caucus over the party's leader appear to be widening as a longtime MPP chastised two of his colleagues for calling on Tim Hudak to submit to a leadership review.

Tory house leader Jim Wilson says it's just a "sideshow" from a small group who "need their heads examined" if they think it's helping the party.

He says some people can't understand that they didn't win the leadership -- an apparent reference to Frank Klees and Randy Hillier, who ran against Hudak in 2009.

Both MPPs have said that Hudak should confront his opponents head-on and allow a leadership vote to silence disgruntled Tories.

Wilson says apart from a few individuals, everyone in caucus supports Hudak, who deserves their loyalty.

He says Klees and Hillier are "misguided" but shouldn't be kicked out of caucus.
