Tim Hudak won't back down from allegations against Kathleen Wynne

Progressive Conservative Leader Tim Hudak is not backing off his allegations that Kathleen Wynne was in charge when a senior Liberal staffer wiped clean 24 computer hard drives in the premier's office.

The Liberals want the accusation removed from Hudak's website and retracted from the record. "The fact of the matter is Kathleen Wynne was in charge. This is much Kathleen Wynne's scandal as it is Dalton McGuinty's," Hudak said in Question Period on Monday.

He said there is evidence of either impropriety or incompetence on Wynne's part.

"I think it's time to get our facts straight," said John Malloy, the Liberal government house leader. He contended Wynne had nothing to do with the allegations and Hudak is not being truthful. "He can repeat [the accusations] as many times as he wants but that doesn't make them true."

Both discussed the scandal on the floor of the legislative house. Wynne was not at Question Period during the exchange. Because Wynne was not present, the NDP walked out in protest.

Hudak says information from the provincial police anti-rackets squad shows the boyfriend of a deputy chief of staff to former premier Dalton McGuinty had an administrator's access to the hard drives after Wynne had become Ontario premier-designate.

He says Wynne was acting as if she were premier in late January 2013, holding meetings and directing government officials, even though she wasn't sworn in until Feb. 11.

Hudak rejects Wynne's claims that she didn't know what was going on in the premier's office until after she officially took over as premier from McGuinty.

Wynne released an open letter Sunday calling Hudak's allegations "false, misleading and defamatory" and demanding he retract the statements and remove them from the PC party website.

Hudak says he is "absolutely not" backing down from the allegations, adding if Wynne didn't know what was going on then she's incompetent.
