No foot movement from Harris as Broad traps him in front with one that kept low, but Harris got a vital bit of bat on it.
Broad revving the engine in this spell. He's bowled his fastest ball of the match (91 mph). The adrenaline is flowing.
Anderson is back into the attack. Can he finish the job that Bresnan, Broad and Swann have started. Aus 188-7
The intensity is high all over the field. Bairstow sprints to the rope and saves four.
Broad softens Siddle up with a couple of short ones and then slips in the yorker. LBW shout but it's sliding down.
Now Harris has a life. His feet are in cement as he insides edges past his stumps and away for four.
That's the recipe for a tailender. Full, fast and straight. That's as plumb an LBW as you'll ever see. Four wickets for Broad.
Swann's back on. With the light fading, have the umpires said "no more pace"?
Apparently not. Broad continues. And Lyon glances him away for four.
The umpires are checking the light.
Broad goes full and the yorker takes out Lyon's leg stump. Superb delivery. That's Broad's 10th wicket in the match.
Swann entices Siddle across his stumps and the Aussie is almost bowled around his legs.
Aleem Dar has his light metre out again. This doesn't look good.
Looks like the umpires have said "no more pace bowling". Joe Root is coming on to bowl.
And he starts with a maiden. Over to you, Mr Swann.
Siddle gets off strike leaving Bird five balls to survive from Swann. Is this the moment?
It should have been. A suicidal single leaves the batsman stranded but Matt Prior fails to gather the throw. Bird would have been out by yards. Aus 213-9.
The sun has returned so Broad is warming up again. In the meantime, Siddle edges Swann just wide of Trott at slip.
Aleem Dar says it's still not light enough for pace bowling so Root continues to Siddle.
No problems for Siddle as he safely negotiates a maiden.
Right, the sun is officially back out. Jimmy Anderson comes back on and Bird pushes him through the covers for a single to get off strike. Then Siddle cuts Anderson for four. It will surprise no one to learn that these Aussies will not go quietly.
Close! Siddle chips one into the leg side but it's just short of Bresnan.
The crowd roar as Broad comes back into the attack. Can he finish it?
HE CAN! Broad clinches the series with his 11th wicket in the match. ENGLAND WIN THE INVESTEC ASHES SERIES 3-0
Siddle spooned a good length ball straight to Anderson at mid off. The England players celebrate. Captain Cook has a souvenir stump. The crowd rises to Broad as he raises the ball to the crowd. 11 wickets. No doubt who man of the match will be.
Day four summary
England clinched a series win with a superb two hours of bowling in the evening session. But, having set Australia 299 to win, the game was very much in the balance until Tim Bresnan snared the crucial wicket of David Warner.
Warner and opening partner Chris Rogers blunted the new ball and put on 109 for the first wicket. At that stage, just before tea, England looked short of ideas and were in danger of losing their nerve.
England regrouped at the break and got their bowling exactly right in a mammoth two-and-a-half hour evening session. When Warner edged Bresnan to Matt Prior to leave Australia 168 for three, they felt the door was ajar.
Then Stuart Broad kicked it off its hinges. Broad topped 90mph as he ripped through Australia's middle order and tail end. 168-3 became 181-7 and Australian hopes were gone. Broad took care of the tail with full, fast and straight deliveries to finish with six wickets, 11 in the match.
When Peter Siddle chipped Broad to James Anderson at mid off, Australia were all out for 224. England won the Test by 74 runs and clinched the Ashes series with a game still to play.
