Bill Gates has admitted to having an affair with a colleague at Microsoft, and stepped down from the company’s board as they investigated his behaviour. An external law firm was hired to address concerns raised by the woman, who was offered “extensive support,” Microsoft said, as further questions about Mr Gates’ workplace conduct have been raised. The affair, which started in 2000 and lasted several years, was brought to the attention of the company in late 2019, the Wall Street Journal reported. Mr Gates resigned from the board in March 2020. He had only been re-elected to his seat three months earlier, but left while still under investigation, the paper added. The result of the probe has not been made public. Mr Gates, 65 and his wife Melinda, 56, are currently engaged in divorce proceedings, with their marriage “irretrievably broken,” according to court documents.
