Federal Liberal Leader Michael Ignatieff on Thursday appointed University of Calgary history Prof. Stephen Randall to be the party's candidate in Calgary Centre-North.

The riding was vacated last year when the Conservative candidate, Environment Minister Jim Prentice,  resigned to take an executive job with CIBC.

Michelle Rempel, the director of the University of Calgary's institutional programs division, won the Conservative Party nomination by acclamation last month.

The Conservatives, with Prentice as the incumbent, have won Calgary Centre-North by overwhelming margins since the riding was created in 2003.

In the 2008 election, Liberal candidate Doug James came in fourth place behind New Democrat John Chan and Green candidate Eric Donovan, with Prentice winning by more than 19,000 votes.
