The federal Liberal leadership race has another high-profile candidate.

Former MP Martha Hall Findlay, who also sought the party's top job in 2006, has come forward on the first official day of the
leadership campaign.

Hall Findlay chose to make her announcement in Calgary.    

She joins Justin Trudeau, who announced his candidacy six weeks ago, and four others.

They include Toronto lawyer Deborah Coyne, Vancouver Crown prosecutor Alex Burton, Ottawa lawyer David Bertschi and David
Merner, former president of the party's British Columbia wing.    

The Liberals are to choose a new leader in April.
