Former Edmonton MLA David Xiao is suing CBC Edmonton, the Wildrose party, and two political commentators for $450,000.

In a lawsuit filed Monday, Xiao claims CBC and Wildrose made statements that meant he had "deliberately and improperly channelled government funds to his political fundraisers, was guilty of corruption, graft and improper use of government monies, (and is) dishonest and unethical."

Xiao is also individually suing CBC reporters Kim Trynacity and Alicia Asquith, former Wildrose leader Danielle Smith and MLA Kerry Towle, as well as social-media political commentators Kathleen Smith of Edmonton and Dave Beninger of Calgary.

Xiao served as the Conservative MLA for Edmonton-McClung from March 2008 until his defeat in May 2015. The lawsuit says his reputation and integrity are "of vital importance to him" and that he has "suffered and will continue to suffer damage to his reputation and feelings."

None of the allegations in the lawsuit have been proven in court and no statements of defence have been filed.
