Andrew Mountbatten‑Windsor was arrested at Sandringham on 19 February on suspicion of misconduct in public office. In a personal statement the King said he had learned with "the deepest concern" of the matter, that "the law must take its course", and that the authorities have the Royal Family’s "full and wholehearted support and co‑operation".

Thames Valley Police confirmed they arrested a man in his sixties from Norfolk at approximately 08:00 and were searching addresses in Berkshire and Norfolk. By 19:31 the force said the man had been released under investigation and that searches in Norfolk had concluded; the National Police Chiefs’ Council said the Home Office was alerted 30 minutes before the arrest in line with routine practice.

Police action follows the release in January of material from the U.S. Department of Justice that, according to media reporting, includes emails apparently forwarded during Andrew’s tenure as the UK’s Special Representative for International Trade and Investment (2001–2011). One message dated November 2010 was allegedly relayed within minutes; another on 24 December 2010 reportedly outlined reconstruction investment opportunities in Afghanistan. Thames Valley Police cited an allegation of misconduct in public office when opening their inquiry. (time.com)
Republic, the campaign group for an elected head of state, says it filed a crime report and had been pursuing a private prosecution; it welcomed the arrest and urged investigators to "follow all evidence wherever it leads". Andrew has consistently denied wrongdoing in relation to previous allegations, and he has not been charged in this case. (republic.org.uk)
Palace sources point to steps already taken last autumn. On 30 October 2025 Buckingham Palace said the King had initiated a formal process to remove Andrew’s style, titles and honours and served notice to surrender the Royal Lodge lease. On 3 November 2025 Letters Patent removed the HRH style and the title of "Prince", and a Royal Warrant directed the Lord Chancellor to remove "Duke of York" from the Roll of the Peerage. (royal.uk)
Constitutionally, removing a peerage outright requires an Act of Parliament; removal from the Roll affects official recognition but does not extinguish the legal dignity. Recent briefings from the House of Commons Library and House of Lords Library set out this position and recap historic precedent under the Titles Deprivation Act 1917. (commonslibrary.parliament.uk)
The alleged offence is tightly framed. Misconduct in public office is a common‑law crime concerning serious wilful abuse or neglect by a public officer "acting as such". Crown Prosecution Service guidance stresses the need to evidence wilfulness and seriousness amounting to an abuse of the public’s trust; the offence carries a maximum sentence of life imprisonment.

Police have also reminded publishers and commentators that the case is now active and care should be taken to avoid contempt of court. That sits alongside the Palace’s commitment to co‑operate while refraining from further comment during the investigation. (thamesvalley.police.uk)
The arrest does not change constitutional arrangements. Andrew remains eighth in the line of succession; removing an individual from the order would require legislation and, by convention, the assent of all Commonwealth realms. Separately, the Counsellors of State Act 2022 added the Princess Royal and the Duke of Edinburgh to the pool of counsellors, reducing practical reliance on non‑working royals. (commonslibrary.parliament.uk)
For officials, the immediate significance is procedural rather than personal. This is a public test of the criminal justice system’s ability to investigate impartially and for the Crown Prosecution Service to take any charging decision on evidence and the public interest. Until then, the legal process-and the King’s instruction that it should run its course-stands. (cps.gov.uk)
