England concede big first innings lead
England batsman Stuart Broad (C) looks towards teammate Tim Bresnan (L) after being dismissed on the third day of the third Ashes cricket Test match against Australia in Perth on December 15, 2013
In reply to the home side's first innings 385, the tourists were were all out for 251 -- a deficit of 134 runs -- 10 minutes before the scheduled interval.
Australia won the first two Tests of the five-match series in Brisbane and Adelaide and can claim the Ashes for the first time since 2007 with victory in Perth.
England resumed at 180 for four on the third morning of play and lost their last six wickets for just 71 runs.
There was little meaningful resistance from the England tail against the pace of Ryan Harris, who took three for 48, Mitchell Johnson (2-62) and Peter Siddle (3-36) once the last of the recognised batsmen Ian Bell (15) and Ben Stokes (18), departed early in the day.
Bell fell lbw to Harris on review, after being initially given not out by on-field umpire Marais Erasmus.
Johnson, man of the match in both of the first two Tests, had gone wicketless despite generating extreme pace, but finally broke through to have Stokes caught behind for 18 as the England newcomer chased a wide one.
Out-of-form wicketkeeper-batsman Matt Prior was caught behind by Brad Haddin off a bottom edge as he tried to pull a short ball from Siddle.
Left-armer Johnson then produced one of the deliveries of the series to remove Stuart Broad for five, with a fast swinging yorker that struck the England bowler a painful blow on his right foot plumb in front of middle stump.
Tim Bresnan hit four boundaries in a breezy 21 before becoming ninth man out with the score on 233.
Graeme Swann needed treatment to his right index finger after being struck on the glove by a Siddle bouncer.
Three balls later Siddle wrapped up the innings when James Anderson could only fend a rising ball to George Bailey at short leg.
