PricewaterhouseCooper's global CEO Samuel DiPiazza, who is in India even as the global auditing firm's role in the Satyam scam is being investigated, called on corporate affairs minister Prem Chand Gupta.

DiPiazza who flew in from Davos was expected to attend the current World Economic Forum.

In a statement PwC confirmed that DiPiazza met the corporate affairs minister but did not elaborate as it was a private meeting.

DiPiazza's visit to India comes in the wake of the firm suspending two of its partners, S Goplakrishnan and Srinivas Talluri, who had were later arrested last week.

The duo had been working on the accounts of scam-hit Satyam Computer Services.

On Tuesday, PwC said that the two have been suspended from the duties as partners pending the completion of investigations into the Satyam case.

Pricewaterhouse also announced the resignation of assurance leader, Thomas Mathew; however Mathew will continue in his capacity as partner of the auditing firm. An assurance leader exercises oversight over audit practices, policies and procedures, and growth and quality control of an audit firm.

Pricewaterhouse said that though Mathew was not directly connected with the audit of Satyam, he believed it would not be appropriate for him to continue in the present circumstances and had relinquished his management position.

A new assurance leader would be appointed in the near future, the company added.
