Dale Steyn celebrates taking the wicket of Ian Bell for 141. The South African bowler found a bit of swing which invited a swipe from Bell and the ball caught a thin edge which is gratefully taken behind by the wicket keeper Boucher Photograph: Gallo Images/guardian.co.uk

A disappointed Ian Bell walks off after losing his wicket, though he has every reason to be proud of his impressive performance in this innings especially after the criticism he faced following the previous Test Photograph: Paul Gilham/guardian.co.uk

Ten overs in of the South African second innings and their first wicket falls. Graeme Swann comes on and on his second ball, Ashwell Prince expects turn on the ball which doesn't come and it grazes his sinside edge and bobbles off his pad and into the outstretched hand of Ian bell at silly point.

In the second over after tea, Kallis leaves a straight one and Broad's delivery rips into the off stump. It's a huge wicket as it means that Kallis is out for just 3 and South Africa are 40-3, and victory is within England's grasp Photograph: Gareth Copley/guardian.co.uk

Following an unsuccessfull referral in the previous over, England finally get their man as Stuart Broad, gets De Villiers for LBW after he scored only 2 runs. We're 19 overs in and South Africa are looking shaky on 43-4 Photograph: Gareth Copley/guardian.co.uk

Four overs later and Broad is on a hat-trick after bowling JP Duminy. The South African batsman looks to leave one slanted across, but fails to move the bat fully away and gets a massive inside edge on to his own stumps. South Africa are now 43-5 Photograph: Gareth Copley/guardian.co.uk
