The current deputy chief minister is the Labor Party's Yvette Berry[1] who took over from former Labor deputy leader Simon Corbell on 31 October 2016, following Corbell's retirement[2] at the 2016 Australian Capital Territory election.

The 1989 ACT election, which was the first under self-government, resulted in Labor emerging as the largest party in the Legislative Assembly with five seats.

[3] Following the formation of the inaugural government ministry under chief minister Rosemary Follett, deputy Labor leader Paul Whalan was appointed to the position.

[6][7] Independents Group leader Craig Duby expected to be elevated to the position, but this never occurred.
