London - Morne Morkel and Dale Steyn have both struck twice to leave England reeling on the second day of the third Test at Lords.
England were 94 for four in reply to South Africa's first innings 309, a deficit of 215 runs, at tea on the second day of the third Test at Lord's on Friday.
Ian Bell was 20 not out and Jonathan Bairstow 19 not out.
South Africa lead the three-match series 1-0 and only need to avoid defeat at Lord's to replace England as the world's top-ranked Test side.
Morne Morkel took his second wicket, removing James Taylor caught behind soon after Dale Steyn had struck twice in four balls to remove Alistair Cook and Jonathan Trott as England slumped.

off the last ball before lunch.
