Just a day after capturing the Leadership of the UCP, Jason Kenney will run in a by-election.

Long time Calgary-Lougheed MLA, Dave Rodney, will step down, allowing Kenney to run.

Kenney says he needs to get into the legislature as quickly as possible.

"Having been elected Leader yesterday (Saturday, October 28), there is a constitutional responsibility for the opposition to be prepared to be an alternative government, and the Leader has to be there."

If Premier Rachel Notley calls the by-election quickly, Kenny could be in the Legislature early in the New Year.

Notley has six months to call a by-election.
