Under scanner for his suspect action, spinner Johan Botha was appointed deputy to captain Graeme Smith for the ICC Twenty20 World Cup.

Even the teen batting sensation Wayne Parnell has also been included in the 15-member South African cricket squad for next month's ICC Twenty20 World Championship in England.

Botha, who has been reported to ICC for suspect action for the second time in his career this year during the one-day series against Australia, has to undergo tests to prove the legality of his action but remains eligible for selection.

The 19-year-old Parnell, meanwhile, created quite a flutter by becoming South African cricketer to bag a central contract.

"The players are all in good form and it is particularly pleasing to have so many quality all-rounders at our disposal. As always, there are a couple of unlucky players and that emphasises the excellent competition we have for places," chief selector Mike Procter said in a statement.

"Form in the Standard Bank Pro20 domestic competition was a key factor in our selection process and it was encouraging to note how high the standard of our domestic cricket is at the moment," he added.

The rest of the squad offers little surprises and has regulars like in-form J P Duminy, Herschelle Gibbs and Jacques Kallis.

The group will gather for a training camp at the end of the month.

The squad: Graeme Smith (capt), Johan Botha (vice-capt), Yusuf Abdulla, Mark Boucher, AB de Villiers, JP Duminy, Herschelle Gibbs, Jacques Kallis, Albie Morkel, Morne Morkel, Justin Ontong, Wayne Parnell, Robbie Peterson, Dale Steyn, Roelof van der Merwe.
