“Whilst our investigation into misconduct in public office continues, we are engaged in legal proceedings in relation to warrants previously obtained from the Central Criminal Court.” Thames Valley Police, in a statement reported on 4 October 2026.
The listing for Thursday afternoon at the High Court in London gives the time, 2pm, and the judge, Mr Justice Hilliard, and then stops being helpful. The hearing is private. The business before the court is not the allegation that produced an arrest in February but the paperwork that came before it: search warrants, their legality, and a police force asking a judge to keep the surrounding documents out of general circulation. Thames Valley Police is attempting to restrict access to court documents, the judicial office confirmed.
The claimant is the King’s younger brother. Andrew Mountbatten-Windsor, second son of the late Queen Elizabeth, is seeking judicial review of the warrants obtained by Thames Valley Police ahead of his arrest on suspicion of misconduct in public office, a challenge first reported by the Daily Telegraph and confirmed on Monday. He was released under investigation. He has not been charged, and he has consistently denied any wrongdoing linked to his association with Jeffrey Epstein.
What makes this a quiet-money story rather than a court story is the sentence that arrived in the same week, from the other side of the family. The lawyers may be instructed. The allowance may not pay them.
Marsh Farm, Sandringham, on a birthday
The arrest happened on the morning of 19 February 2026, which was his 66th birthday, as Variety reported at the time. The underlying allegation concerns the trade role he held between 2001 and 2011: Thames Valley Police had earlier said it was assessing reports that he sent confidential trade reports to Epstein in 2010, when he was Britain’s special envoy for international trade, according to PBS NewsHour. Assistant Chief Constable Oliver Wright said the force had opened an investigation into the allegation of misconduct in public office following a thorough assessment, and acknowledged the public interest in the case.
For several days afterwards, officers were seen at two addresses: Marsh Farm on the Sandringham estate, where he now lives, and Royal Lodge on the Windsor estate, where he used to. The warrants, by the force’s own account, came from the Central Criminal Court.
The historical footnote is the detail that travels at dinner. It was the first arrest of a member of the British royal family on a criminal warrant since Charles I, after the English civil war.
The King’s response in February was eleven words long in the part everyone quoted: the law must take its course. He added that it would not be right for him to comment further, and that his family would continue in their duty and service. Palaces rarely say less than that and almost never say more.
Thirty rooms in Windsor Great Park
The second address the police searched had been home since 2003. The Times reported that he had not paid rent on the 30-room mansion for two decades, but had funded at least £7.5 million of renovations when he moved in, a point carried in the ABC’s coverage of his departure. One published account describes the lease as running to 2078, a term that was widely considered cast iron until it wasn’t.
On 30 October 2025, a statement issued on behalf of King Charles and Queen Camilla began the formal process of removing all his titles, including prince, two weeks after he had announced he would stop using them while denying the allegations against him. The same statement served formal notice to surrender the lease, with a move to alternative private accommodation. PEOPLE confirmed he left Royal Lodge in early February 2026. Sarah Ferguson, his former wife, had been living there with him and had to find somewhere else.
Reports suggested a payment of close to $728,000 connected to the living arrangement. The Daily Mail reported he would be denied most of it, because a great deal of work on the property remained undone. No confirmation of any final figure has been published.
So the sequence runs like this. He gave up the house in early February. Police searched both the new address and the old one later the same month.
Buckingham Palace draws a line around the bill
The funding story broke in the same news cycle as the judicial review, which is not how coincidences usually work in Windsor. According to the Telegraph, a Buckingham Palace source said the King had no involvement in the legal action and that it had been “made clear” that the private allowance he receives from the monarch should not be used to fund it. The same reporting describes that allowance as an annual six-figure sum from the King’s private funds, including money towards private security.
The Palace had already said that taxpayers would not cover his legal costs. With this week’s line, both doors are now shut: not the Treasury, and not the brother. An allowance is a relationship with terms, and the terms have just been written down.
The cost is the part nobody can pin. The legal action against Thames Valley Police could reportedly run to hundreds of thousands of pounds, a single-sourced estimate carried by 1News from the Telegraph’s reporting, and not a figure from any costs filing. Nor do the allowance numbers reconcile. A 2025 biography excerpt claimed the King had instructed the Keeper of the Privy Purse to remove a £1 million annual personal allowance and to stop paying for personal security; that account and this month’s six-figure reporting have never been squared in public, and may describe different streams or a renegotiated arrangement.
As for what he is actually worth, the honest answer is that nobody outside the family knows. Celebrity-finance aggregators have published estimates ranging from about $2 million to roughly £3.7 million, and the same sites give his only known income as a £20,000 annual military pension. None of it comes from an audited or primary source, and none of it should be read as one.
The scale of the institution’s money is not in question. The Sovereign Grant allocation for 2025-26 exceeded $176.6 million, an increase of more than $61 million on the previous year, and the Privy Purse, the King’s private funding mechanism, reached over $38 million in 2024-25. The argument has never been about whether the money exists. It is about which pot is permitted to touch which lawyer.
What is actually at stake on Thursday
A judicial review of search warrants is not a verdict on anything. It is an argument about whether a judge should have granted the warrants in the first place, and about what happens to the material seized under them.
The legal commentator Vamos has pointed out that police can apply back to the Crown Court to retain material if they have grounds to seize it again immediately, and that forcing a return would require a more fundamental problem with the way the warrants were granted. Which is to say the upside, even at full success, is narrower than the headlines suggest.
The royal biographer Andrew Lownie has offered a different reading of the purpose: that the move against Thames Valley Police could function as a signal, discouraging the force from pursuing its investigations with such vigour in future. That is one author’s interpretation, not an account of the pleadings, which nobody outside the room has read.
Thursday’s listing concerns the force’s bid to restrict access to the documents, and whether he will attend has not been confirmed. The substantive question sits behind it, in a case brought by a man who no longer holds the titles, no longer holds the lease, and has been told in terms which money he may not spend on it.
The hearing is at 2pm, in private, before Mr Justice Hilliard. The misconduct investigation, Thames Valley Police says, continues.
