Lord Peter Mandelson, the former Labour minister and European Commissioner, was arrested on February 23 on suspicion of misconduct in public office, according to reports.

The arrest followed information passed by Commons Speaker Sir Lindsay Hoyle suggesting that Mandelson was considered a flight risk. As part of the investigation, his passport was reportedly confiscated.

Mandelson's legal status has since been updated from being on bail to being released under investigation, indicating the ongoing nature of the case without the formal bail conditions.

The specific details of the alleged misconduct have not been disclosed by authorities. Mandelson, who served as a senior figure in Tony Blair's government and later as EU Trade Commissioner, has not publicly commented on the matter.

Being released under investigation is a standard police procedure that allows continued inquiry without the restrictions of formal bail conditions, while the suspect remains free to go about their daily activities.
