Right, on that bombshell it's time for us to leave you. We will see you for the fourth Test in Centurion on Friday morning.

You can read a full report in the day's action here.

Until then, goodbye.

Michael Vaughan
Ex-England captain on BBC Test Match Special

"This team is very handy to captain. I wouldn't mind captaining them, that's for sure.

"When you're up against a team that has that knack of losing the key moments you make the most of it.

"England are on an upward curve, in all formats. The group is gaining more experience and, although I don't want to shout about it too much, England are on the pathway of becoming a really powerful team across all the formats."

"I expected South Africa to lose the series, even if Steyn and Philander were fit. There are lots of kind words like transition and there have been some wonderful players.

"But this is one of the all-time lows since readmission to international cricket. They have to look around and make some honest assessments."

"The best side stood up to be counted when the pressure was on, and that was England. South Africa have all the problems now. England are playing well - there is no reason to change anything unless Finn has an injury."

More from Alastair Cook on Sky Sports: "It hasn't sunk in yet at all. We knew today would be 'moving day' in a sense. The plan was to get level with them and then pile pressure on with the ball. 

"Trev [Bayliss] gave us a rocket and said, 'If you want to win the series, go now and go hard.' I can't take any credit for man-managing Ben Stokes. He's an absolute gem for a side: the ability to score 250 one day and bowl 90mph the next. 

"Everyone in that dressing room can be very proud of their contribution in this series. I'm really pleased for all the lads."

"Hales is a problem. He does not have the technique for Test cricket. You have to have a reasonably decent technique to play good balls, but his feet are all over the place.

"Unless he improves his footwork, I don't think he'll make consistent runs. Over a period he will have a number of failures."

First Test, Durban: England won by 241 runs

Second Test, Cape Town: Match drawn

Third Test, Johannesburg: England won by seven wickets

Fourth Test, Centurion: 22-26 January

Howard Horner:  It's a shame that Steyn and Philander were absent for SA, but even with them, on their day this side can beat anyone.

"Broad destroyed them. He was running in like a cheetah. The ball that De Villiers out was a crackerjack and he is the best player in the world. He has this ability to get a match-winning performance decisively. He bowled people out with quality balls. He had them five down for nowt - game over."

Stuart Broad is named man of the match for his performance of 6-17 in the third innings.

He says: "I was under the weather on the first day. Everyone we know has been ill at some stage over the past few weeks.

"In the first innings I bowled a bit too short. We had a chat before the second innings and talked about bringing the batsmen forward a lot more. 

"We got lucky today - it was perfect conditions to bowl, but we also got the ball in good areas and took our chances.

"I was quite tired towards the end. Finny was trying to get on and I was trying to get off. I got in a rhythm and it was a good day to bowl. There was a bit of bounce there too. I wish I could take that wicket around with me."

More from Alastair Cook: "I don't tell Stokesy anything, I just let him play, those two did exactly the same against New Zealand last year. We also took our catches - we made a conscious effort to practice it between the Tests.  Andrew Strauss told us to have a big one tonight and if he says so, we're going to have to."  

England captain Alastair Cook: "To come here and beat South Africa is a huge achievement for the lads, they can be very proud.

"In the first session of the match we didn't quite get it right with the ball, but credit to the guys, they bounced back pretty well and kept South Africa to about par. Joe Root played exceptionally well to get us to about a par score, and then it was over to Broady, who just got one of his rolls."
