A High Court judge has been given "formal advice" after "momentarily" falling asleep during a hearing.

The Judicial Conduct Investigations Office (JCIO) said the conduct of Mrs Justice Parker was found to have the potential to undermine public confidence in the judiciary.

The judge, 68, who serves on the Family Division of the High Court in London, was investigated following a complaint.

The JCIO said she "expressed remorse" for the incident.

A statement published on the JCIO's website did not provide details about when the court hearing took place but said "parties in a case" had complained the judge had fallen asleep.

Lord Chancellor David Gauke and Lord Chief Justice Lord Burnett considered her conduct.

The JCIOsaid: "While concluding that this amounted to conduct which had the potential to undermine public confidence in the judiciary, the Lord Chancellor and the Lord Chief Justice took into consideration that the judge fell asleep only momentarily and has expressed remorse for doing so."

Mrs Justice Parker is the second longest-serving judge serving in the Family Division of the High Court, after being appointed in 2008.
