The Australian Prime Minister slammed the third umpire's controversial decision to give Australian batsman Usman Khawaja out - after he was caught behind in the third Ashes Test at Old Trafford.
Kevin Rudd was furious with the call, which was made after Khawaja reviewed the initial decision by on-field umpire Tony Hill, who gave him out.
The Decision Review System suggested that he had not nicked the ball, with no mark appearing on Hot Spot, but third umpire Kumar Dharmasena opted not to change the decision.
Rudd took to Twitter to vent his anger, and the decision left the visitors on 82-2 in the morning session on day one of the Test.
He tweeted: "That was one of the worst cricket umpiring decisions I have ever seen."
This is not the first time that the Aussies have fallen foul of a questionable decision.
Spin bowler Ashton Agar was given out in similar circumstances in the second test at Lord's.
Agar was given out after being caught behind despite no mark showing up on Hot Spot, which has led to the DRS coming under much scrutiny so far this series.
Rudd was not the only unhappy Australian, as former Australia bowler and now Sky Sports commentator Shane Warne said: "That's a shocker, that's an absolute shocking decision."
The tourists must win the Test to stand any chance of winning the series, as they currently trail 2-0 with two matches left to play after this one.
