England have only got one review left and Stuart Broad is bowling...

Stuart Broad brings out the celebrappeal as the ball cannons into Dean Elgar's pads.

Umpire Nitin Menon is having none of it, though, and England decline the review. Height looked an issue there.

Broad repeats the trick two balls later, but this looked to be drifting down leg.

Still, some encouragement for Broad as he repeatedly beats Elgar's bat.

Ben Stokes may have taken a wicket before lunch but he is not going to continue. Instead he turns to James Anderson, who once again gets the ball to rise off the pitch and beat the outside edge of Keegan Petersen's bat.

The next ball Petersen plays a lovely backfoot push through the covers for his third four of the session. Petersen has raced onto 19 from 19 deliveries.

Only once in his extremely long career has Stuart Broad conceded more runs in his first four overs of an innings than the 27 he has here.

Another boundary for Keegan Petersen. This was a slightly riskier shot as he goes for an uppish cut that flies just over James Anderson at backward point.

A good start to the afternoon session for South Africa.

Lovely shot from Keegan Petersen. He is offered a bit of width by Stuart Broad and he clatters the ball through point for four.

Here come the players to the middle. A similar session for South Africa here and they will be in a dominant position.

With England searching for inspiration skipper Ben Stokes turned to himself - and he immediately made an impact.

Sarel Erwee edged through to Joe Root at first slip, who took a smart catch. England will feel that is the least they deserve for their efforts.

England impressed with the ball and beat the outside edge on a number of occasions, in sharp contrast to Saturday when everything they tried seemed to turn to wickets.

South Africa captain Dean Elgar has led the Proteas' resistance from the front. He is still at the crease after battling his way to 35 from 54 deliveries.

South Africa went into the day wanting to remove England's final three wickets cheaply to keep their first-innings lead as small as possible.

Boy did they do that.

Ollie Robinson went with just the second ball of the day. Jack Leach swiftly followed. And when Ben Foakes was dismissed by Marco Jansen England were all out having added just four runs in the space of 13 minutes.

Thanks, Ffion.

What a difference 24 hours makes. South Africa were 69-6 at lunch yesterday. Today they are 70-1 and in a position where they can set England a challenging target.

Though as England keep reminding us, a tricky run chase is not something they will be intimidated by.

As the players depart for their lunch break, it's time for me to hand over to Tom Mallows who will guide you through the interval and the afternoon session.

South Africa will just try and bat. They have to pick up runs wherever they can and increase that lead as quickly as possible. If you had offered South Africa a lead of 30 with nine wickets left at the start of play they would have said we hadn't considered that as a possibility in our wildest dreams.

A nice little flurry of runs before lunch for South Africa as Keegan Petersen drives nicely down the ground, but Stuart Broad does well to save the boundary. They run three.

Another fascinating session. It wasn't pretty from South Africa, they had to dig in and withstand some really good bowling from England. They will have been disappointed to lose the wicket of Sarel Erwee, but it's still been their session after taking England's remaining three wickets so quickly.

Here's how England took their first wicket, after Dean Elgar and Sarel Erwee added 58.

1. Rahul Dravid (Ind) - 210
2. Mahela Jayawardene (SL) - 205
3. Jacques Kallis (SA) - 200
4. Ricky Ponting (Aus) - 196
5. Mark Waugh (Aus) - 181
6. Alastair Cook (Eng) - 175
7. Stephen Fleming (NZ) - 171
8. Graeme Smith (SA) - 169
9. Brian Lara (WI) - 164
10. Ross Taylor (NZ) & Joe Root (Eng) - 163

Stokes continues to bowl very full but without much effect. A couple drift down the leg side and the last ball of the over is on leg stump and Dean Elgar clips it effortlessly for four.

South Africa can win this game. They have a reputation for backs-to-the-wall blocking but this scenario doesn't suit that. They can win but have to take every run they can.

The sun is just trying to creep through overhead and with the ball getting older, it may start to get easier to bat for South Africa.

Ben Stokes, though, will have other ideas.

James Anderson, aged 40, has just beaten Ben Stokes in a chase to the boundary. Stokes wasn't taking it easy, either.
