Nilekani back at Infosys as Chairman, Seshasayee quits

Ravi Venkatesan also resigned as co-chairman, but will continue as an independent director.

Vishal Sikka, who quit last week as CEO but was made vice-chairman till his successor was appointed, also quit the board with immediate effect, the company said in a statement after its board meeting.

The board shake-up meets a key demand of the founder group led by N R Narayana Murthy, who had demanded a clean-up at the country's second largest software services firm.

Two independent directors -- Jeffery S Lehman and John Etchemendy -- also resigned from the Infosys board with immediate effect.

The crisis had been brewing at Infosys since Sikka abruptly resigned last week, blaming founders for slander.
