The Liberals, Progressive Conservatives and Green parties have all been left out of the Saskatchewan leaders' debate.

Liberal Leader Darrin Lamoreux says he's upset his party isn't going to be included in Wednesday night's debate.

Lamoreux says the media consortium running the debate is doing a disservice to the public by limiting the full range of views and options available to voters in the election to be held on April 4.

The Liberals, who didn't have a seat in the legislature when the writ was dropped, are running a full slate of 61 candidates.

PC Leader Rick Swenson and Green Party Leader Victor Lau are also not allowed in the debate.

A petition on change.org asks people to urge the media consortium to include Lau.
