Saikawa’s fate to be discussed by board on Monday after admission that he was overpaid by hundreds of thousands of pounds

The chief executive of Nissan, Hiroto Saikawa, has said he will resign, Japanese media reports have said, after he admitted being improperly overpaid in the latest upheaval to hit the Japanese vehicle maker.

Saikawa’s expected resignation, reported on Sunday in the Nikkei daily business newspaper, comes as the company attempts to cope with the fallout from the arrest last year of its former chairman Carlos Ghosn over allegations of financial misconduct.
