Cricket: South Africa v England - fourth Test, day two

With South Africa aiming to build on yesterday's performance, they start the day well with captain Graeme Smith nudging up his score to 41 over the first 16 overs of the day's play

The fact that he managed to reach that figure is thanks to a controversial referral decision. In the 16th over, Smith was caught behind but given not out and England called for a referral. When Smith played his shot there was a noise - a noise that could not have been anything else but bat on ball - but Daryl Harper, acting on the audio feed his was given as third umpire, upheld the decision, telling the umpires there was no noise

After the disappointment of not getting the decision on Smith, England bounce back and immediately take their first wicket of the innings. Stuart Broad delivers a very good off-cutter to Ashwell Prince, who edges the ball towards Graeme Swann at second slip. Prince is out for 19 and South Africa are 36 for one

Broad is all smiles after taking the wicket. Broad had a good morning session but unfortunately so did the hosts, as they are 160 for 1 at lunch
