Tom Mulcair, Justin Trudeau and Gilles Duceppe have all agreed to appear on a popular Quebec television show that traditionally garners bumper ratings.

A spokeswoman for Tout le monde en parle says Conservative Leader Stephen Harper has declined an invitation to go on the talk show.

Jack Layton's appearance on the program in the 2011 election campaign is credited with helping the NDP make its stunning surge in the province a few weeks later.

Mulcair will be on the show on Oct. 4, while Trudeau and Duceppe will appear separately on Oct. 11.

Harper spokeswoman Catherine Loubier says she does not comment on interview requests.

The weekly Radio-Canada program Tout le monde en parle features various guests, with many of them enjoying a glass of wine as they exchange pleasantries.
