Whitlam had offered Barnard a diplomatic post; in early 1975 Barnard agreed to this, triggering the 1975 Bass by-election in his Tasmanian electorate. The election on 28 June proved a disaster for Labor, which lost the seat with a swing against it of 17 percent. The next week, Whitlam fired Barnard's successor as deputy prime minister, Cairns, who had misled Parliament regarding the Loans Affair amid innuendo about his relationship with his office manager, Junie Morosi. At the time of Cairns' dismissal, one Senate seat was vacant, following the death on 30 June of Queensland ALP Senator Bertie Milliner. The state Labor party nominated Mal Colston, resulting in a deadlock. The unicameral Queensland legislature twice voted against Colston, and the party refused to submit any alternative candidates. Bjelke-Petersen finally convinced the legislature to elect a low-level union official, Albert Field, who had contacted his office and expressed a willingness to serve. In interviews, Field made it clear he would not support Whitlam. Field was expelled from the ALP for standing against Colston, and Labor senators boycotted his swearing-in. Whitlam argued that, because of the manner of filling vacancies, the Senate was "corrupted" and "tainted", with the Opposition enjoying a majority they did not win at the ballot box.
