Sikka, who had joined Infosys in August 2014, said these distractions were preventing the management's ability to accelerate the company's transformation.
While he didn't detail out these "distractions", it may be noted that some of Infosys founders, including N R Narayana Murthy, have alleged corporate governance lapses at the firm and questioned the high compensation paid to Sikka and severance package extended to certain former executives.
The stand-off between the founders and management has been on for a few quarters now, with both sides making public statements on these issues.
Sikka, in a letter to the board members, today said "false, baseless, malicious and increasingly personal attacks" have been made over the last many quarters and these allegations have been repeatedly proven false by multiple independent investigations.

"But despite this, the attacks continue, and worse still, amplified by the very people from whom we all expected the most steadfast support in this great transformation," Sikka said.
The board said it is "profoundly distressed" by the unfounded personal attacks on the members of the management team.
"The board denounces the critics who have amplified and sought to further promote demonstrably false allegations, which have harmed employee morale and contributed to the loss of the company's valued CEO," Infosys said in a statement.
Sikka will be Executive Vice Chairman effective today, and will hold office until the new CEO and MD takes charge, which should be no later than March 31, 2018. He will report to the company's board and draw a salary of USD 1.
