## Calgary-Foothills

Following the Alberta Progressive Conservatives' defeat in the 2015 provincial election, outgoing premier Jim Prentice announced on election night that even though he had personally won re-election in Calgary-Foothills, he was resigning his seat in the legislature. This had the effect of voiding the election result, and necessitated the calling of a by-election to fill the seat.
The by-election to succeed him was scheduled for September 3, 2015, and was won by Prasad Panda of the Wildrose Party. Panda's victory increased the Wildrose caucus to 22 members in the Legislature, and kept the Progressive Conservatives at 9.
