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.
Mr Justice Hilliard said on Thursday that while the former Duke of York and Thames Valley Police had reached an “agreement” that the warrants were unlawful, police have since launched a bid to retain evidence gathered during the searches in February.
