OTTAWA -- Another French-language election debate will be held next month in Montreal.

The debate sponsored by a broadcast partnership which includes Radio-Canada, Tele-Quebec, CBC News, CTV News and Global News, along with La Presse, will be held Sept. 24 in Radio-Canada studios.

It will include Conservative Leader Stephen Harper, Tom Mulcair of the NDP, Justin Trudeau of the Liberals, Green party Leader Elizabeth May and Gilles Duceppe of the Bloc Quebecois.

The debate will be available across the country with simultaneous translation.

Quebec television journalist Anne-Marie Dussault will moderate the debate with questions to be posed by Patrice Roy, a Radio-Canada anchor, and Yves Boisvert, a journalist from La Presse.

The partnership says in a statement that discussions to produce an English-language leaders debate Oct. 8 are ongoing, although a spokesman for the Conservative party says the Sept. 24 debate is the last one it will agree to.

Earlier Tuesday, the NDP said Tom Mulcair will take part in a bilingual election debate sponsored by the Munk Debates in Toronto on Sept. 28.

The party leader has been selective about debates, saying he will only take part in those that include Harper. Mulcair said last week his team was weighing about two dozen debate proposals and promised a decision by Monday.

With Mulcair's announcement that he had agreed to participate in the Munk debate on foreign affairs, all three major party leaders had signed on to participate.

Harper agreed to the Munk debate earlier. The Liberals said leader Justin Trudeau would also participate in the debate, but are asking that Elizabeth May be included as well.

The Green party leader was not invited, despite her well-received participation in the first election debate.

Trudeau has said the more debates, the better.

In addition to requiring Harper's presence, Mulcair has also said one of his debate conditions is that there be an equal number in English and French.

Harper, for his part, has rejected the traditional debates run by a consortium of the major broadcasters. He has also agreed to a Sept. 17 Calgary debate sponsored by the Globe and Mail and Google Canada and a French-language debate on Quebec's TVA network on Oct. 2.
