TOKYO -- Toshiba will hold an emergency board meeting on Sunday to address a commissioned report that concluded that the company's annual shareholders meeting last year was "not fairly managed."

An independent investigation, conducted by three lawyers, looked into alleged voting irregularities. Thursday's report found that the Japanese conglomerate had closely worked with the Ministry of Economy, Trade and Industry to pressure activist shareholders .

Toshiba's supervisory committee had said that a review of the 2020 shareholder meeting found no problems, a position contradicted by the findings. "We will carefully review the findings" and respond at a later date, Toshiba has said of the report.

With the head of the supervisory committee among the board members up for reappointment this year, some shareholders have voiced their opposition.

The slate of directors to be voted on at this year's general shareholders meeting on June 25 will be discussed at the emergency board meeting as well.
