John Edwards, the UK's information commissioner, has resigned following a workplace investigation.
- +UK's top AI regulator quits after 'inappropriate' humour
"I have accepted that there have been occasions where I exercised poor judgement and made attempts at humour that were inappropriate and caused offence," he said in a statement on Friday.
"I have accepted that there have been occasions where I exercised poor judgement and made attempts at humour that were inappropriate and caused offence," he said in a statement on Friday.
The Information Commissioner's Office (ICO) is responsible for regulating AI in the UK and also oversees data protection regulation and the freedom of information law.
The BBC has approached the ICO and the government for a response.
Edwards, who had been at the watchdog since January 2022, had already stepped back from his post in February when the investigation started.
In his statement, shared on his LinkedIn page, he said while he disagreed with how the ICO's investigation had been carried out, "I accept that my position has become untenable".
He said he did not want to become "a distraction" from the ICO's work and had notified the government of his resignation as both commissioner and chair of the ICO "effective immediately".
The ICO said in a statement on 10 June its investigation had been completed and, finding "there is a case to answer", said the commissioner would be "temporarily unable to act in fulfilling his responsibilities for the remainder of the process".
It comes amid increased scrutiny over the ICO's work, particularly in dealing with data protection complaints from the public.
Non-profit campaign groups the Good Law Project and the Open Rights Group (ORG) recently launched action to challenge the watchdog - accusing it of "brushing aside thousands of public data complaints".
"John Edwards' departure is a chance for the Government to appoint a regulator with teeth, and reset the regulators' approach of providing data protection in name only," ORG executive director Jim Killock said on Friday.
"Parliament must ensure that the future Commission is run by professionals who want the law enforced, including against government data failures."
Edwards said in his statement on Friday he was "proud" of his own contributions and that of ICO staff, more broadly.
"While I will no longer be able to continue this work in my current role, my commitment to the principles, values, and objectives that have guided my professional life remains unchanged," he added.
