Mohammad Irwan Serigar Abdullah has been dropped from Bank Negara Malaysia's board of directors with effect from May 14.

According to Bank Negara, his removal stemmed from the fact that he was no longer Treasury secretary-general.

On May 14, Irwan was transferred to the Public Service Department and put in cold storage pending the expiry of his contract on June 13 this year.

Under the previous BN administration, he sat on the boards of many GLCs, including 1MDB and Petronas.

He is also the chairperson of Retirement Fund Incorporated (KWAP), Cyberview Sdn Bhd and MRT Corp.

Irwan also chairs the Inland Revenue Board (LHDN). At the time of writing, however, the chairperson's name on the LHDN website has been left empty.
