The election saw Gunner retain the seat for the Labor Party by only a slight margin, over Garry Lambert, former alderman and acting Lord Mayor. On 19 April 2015, Gunner announced he would stand for the leadership of the Northern Territory Labor Party against incumbent Delia Lawrie, who was facing criticism of her conduct during an inquiry into a property deal while she was a minister. Four days later, Lawrie resigned and Gunner was elected unopposed as leader.
