Federal NDP candidates make final appeal ahead of leadership vote

HAMILTON — The four federal NDP leadership hopefuls have one last chance today to make their case to party voters before balloting begins to select a replacement for outgoing leader Tom Mulcair.

Manitoba MP Niki Ashton, Quebec MP Guy Caron, Ontario MP Charlie Angus and Ontario legislature member Jagmeet Singh will take part in a leadership showcase today at a caucus retreat in Hamilton, Ont.

Each candidate will have 22 minutes to present their plan for the federal party.

New Democrat national caucus chair Daniel Blaikie says that once the leader is chosen, the party will have a new voice to carry their message to Canadians.

The NDP announced in August that party membership had more than tripled since March, from 41,000 to 124,000 card-carrying New Democrats.

Members of the NDP will vote for Mulcair's successor starting Monday with results to be announced in early October.
