King Charles III will not allow the financial support he provides to his brother Andrew Mountbatten-Windsor to be used for a legal challenge against police actions, a source familiar with the matter told RIA Novosti.
The king continues to provide his brother with some financial support but has made clear that it cannot be used for the court case against police, the RIA source said. The report did not cite a public comment from Buckingham Palace.
The Daily Telegraph earlier reported that Andrew had asked a court to determine whether police acted lawfully during his arrest, including whether search warrants were valid. A closed hearing this week is due to decide whether documents related to his claim should be made public.
Mountbatten-Windsor was arrested in late February in a case alleging misconduct in public office while he was a trade envoy. The allegation concerns the forwarding of government documents to U.S. financier Jeffrey Epstein. The allegations do not establish guilt.
Charles III stripped his brother of all his titles in early December 2025. The current legal action concerns police conduct and access to court documents. According to the RIA source, the king’s financial support is not intended to pay for the proceedings.
