IT major Wipro on Friday announced that it has appointed Thierry Delaporte as chief executive officer and managing director. He will take charge on July 6. Incumbent Abidali Neemuchwala will relinquish charge on June 1 after four years; the Texas-based executive had announced his decision to step down in February, citing family commitments. Chairman Rishad Premji "will oversee the day to day operations of the company until July 5", a company statement said. The markets reacted to the news positively, with the Wipro scrip ending 6.65% higher over the previous day's close.
