Managerless Leeds claimed a first away win in five matches with a comfortable victory over nine-man Bristol City.
Robert Snodgrass gave Leeds the lead with a low shot, before City's James Wilson was shown red for bringing down Scottish striker Ross McCormack.
City were down to nine men when Yannick Bolasie was shown a second yellow.
McCormack added a second for Leeds when he struck home an angled shot before Luciano Becchio completed the scoring by converting Aidan White's cross.
Against a Leeds side playing their first game since the midweek sacking of Simon Grayson, City were the first to provide excitement following a scrappy opening period.
Leeds keeper Andy Lonergan went full stretch to keep out Bolasie's strike, before being tested by a powerful drive from Elland Road old boy Neil Kilkenny.
Lonergan was again called into action to keep out Albert Adomah's angled drive.
However, the tide turned once Snodgrass had given Leeds the lead, against the run of play in their first meaningful attack just before the break, wrongfooting home keeper David James after a swift break involving Becchio, Danny Pugh and McCormack.
Leeds were then not only a goal up at half-time, but a man up too, when City had Wilson sent off.
And he was followed down the tunnel by Bolasie, in the 57th minute, for two challenges on loan signing Adam Smith.
Leeds then dominated the rest of the game, striking twice in the final 11 minutes to secure a victory which lifts them to ninth in the Championship, just four points adrift of a play-off spot.
