The husband of a woman missing for three days from her Berkshire mansion has been charged with her murder.
Joanna Brown, 46, who runs a bed and breakfast from the mock-Tudor home in Ascot, was reported missing on Monday.
Police searches are being carried out in nearby Windsor Great Park, home to The Queen's Windsor Castle residence.
Robert Brown, 46, of North Street, Winkfield, was remanded in police custody and is due to appear before Slough Magistrates' Court on Friday.
Police said they had received new information on Thursday afternoon that had led them to search an area of the park, which is owned by the Crown Estate and covers 5,000 acres (20 sq km).
Officers said searches would continue throughout Friday.
On Wednesday, Mrs Brown's family appealed for information, describing her as a "very special person, loved and admired by everyone who knows her, a wonderful and caring mother to her two children".
