A 34-year-old man has been charged with the murder of a multi-millionaire hotelier, one of the UK's richest men.
Sir Richard Sutton died at his home near Gillingham, Dorset, on Wednesday. His partner, Anne Schreiber, was also stabbed and is in a critical condition.
Thomas Schreiber was charged with murder, attempted murder and dangerous driving.
The wealth of Sir Richard, 83, and his family was valued at £301m in the 2020 Sunday Times Rich List.
Mr Schreiber is due to appear before magistrates in Poole on Monday.
Detective Inspector Simon Huxter, of Dorset Police, said: "Our thoughts remain with the victims' family and all of those affected by this terrible incident.
"Following a detailed investigation, we have consulted with the Crown Prosecution Service.
"As a result, Dorset Police have been authorised to formally charge Thomas Schreiber with the murder of Sir Richard, attempted murder of the injured woman and dangerous driving."
A spokesman from the businessman's company, Sir Richard Sutton Limited, said on Sunday: "Our thoughts are with Anne Schreiber, who remains in a critical condition in hospital and was a hugely important part of Sir Richard's life, especially in his later years.
"After caring for Sir Richard for a long period, we in turn wish her a swift and full recovery.
"Though separated, Sir Richard also remained on good terms with his wife, Lady Fiamma, and very close to their children, who are mourning the loss of a devoted father.
"Employees across the group have been united in their shock at what has happened and will need time to come to terms with the loss of such an influential figure."
Sir Richard, who was number 435 in last year's Sunday Times Rich List, owned a string of top hotels.
The baronet had an extensive property and farming portfolio, including owning the freehold of the Sheraton Grand London Park Lane and the Athenaeum Hotel in Mayfair.
