Andrew Mountbatten-Windsor remains locked in a High Court battle over whether evidence obtained during raids of two of his properties can be used in the criminal investigation into him after police acknowledged the search warrants used were unlawful.
The former Duke of York, who was not present at the hearing, launched a legal claim against the force over the lawfulness of search warrants granted to them by a judge at the Old Bailey in February, which led officers to raid his residence on the Sandringham Estate and his former Windsor home, Royal Lodge, in February.
