Former infrastructure minister Ric McIver is the new interim leader of the Alberta Progressive Conservative party.
The party says McIver was chosen by members of the PC caucus, which was reduced from 70 members to 10 in the provincial election last Tuesday.
Leader Jim Prentice resigned immediately after the defeat.
McIver finished second to Prentice last year in the PC leadership race.
McIver says he is honoured that his caucus colleagues have chosen him to lead the party as it works to rebuild.
It is not immediately clear if McIver, who was re-elected in the Calgary-Hays riding by a healthy margin, will run to succeed Prentice.
McIver, who is 56, is a former Calgary city alderman who has also served in cabinet as minister of transportation.
