Party president Brian Topp is scheduled to make an announcement this morning in Ottawa.
He'll be joined by NDP MP Francoise Boivin.Topp's name surfaced early as a possible contender in the NDP leadership race.
The fully-bilingual Montrealer has worked in NDP backrooms for years, and was a close confidant to Layton, who died last month of cancer.
The NDP is set to hold a caucus retreat starting tomorrow in Quebec City.
