Kevin Pietersen must wait to discover whether the International Cricket Council decide to investigate his controversial remarks about his sport in South Africa.

Hampshire's mercurial middle-order batsman has reiterated his complaints about the racial quota system in his native country, adding his own views on the match-fixing scandal which enveloped disgraced former South Africa captain Hansie Cronje.

An ICC spokesman today declined to comment further other than to confirm the world governing body have received a letter from Cricket South Africa asking for an investigation into Pietersen's views, which have been published in GQ magazine.

Should Pietersen, 60 not out overnight at the end of day one of the second Ashes Test in Adelaide, be called to account for his remarks and disciplined by the ICC for 'inappropriate public comment', the scale of punishment goes as far as a ban for four Test matches or eight one-day internationals.

A spokesman insisted it would be inappropriate to speculate on the ICC's response but did say: ''I can confirm we have received a letter from Cricket South Africa in relation to this.''
