Labor senator to run for lower house

Katy Gallagher is expected to return to her ACT seat in the Senate after her leading contender pulled out to run for the House of Representatives.

ACT Labor senator David Smith will run for the lower house seat of Bean at the next federal election, following Labor MP Gai Brodtmann's decision to retire.

Senator Smith replaced Katy Gallagher in the upper house after she was disqualified over her dual citizenship.

The move means Ms Gallagher will be preselected by Labor to return to the Senate at the next election.
