OTTAWA -- The NDP has chosen two high-profile MPs to be the architects of its 2015 election strategy.

Jean Crowder and Alexandre Boulerice have been named co-chairs of the NDP's national campaign.

It will fall to Crowder and Boulerice to lead the NDP's planning and preparations for next year's campaign, in which the party hopes to build on gains in the 2011 federal election that saw it become the official Opposition for the first time in its history.

NDP Leader Tom Mulcair made the announcement Sunday in Ottawa at a weekend meeting of the party's federal council.

During the stump-style speech, Mulcair took swipes at Prime Minister Stephen Harper and Liberal Leader Justin Trudeau.

This weekend, the NDP also chose veteran party strategist Anne McGrath to be its national director, replacing Nathan Rotman, who left to work on former NDP MP Olivia Chow's Toronto mayoral campaign.
