West made millions by setting up the Calais-based discount alcohol and tobacco business Eastenders.
He also founded his own wine label, The Dog’s B*******, and ran a nightclub and restaurant in London’s Mayfair.
West, 70, was found with a single fatal stab wound at his Mayfair home just after 6pm on Friday, December 12.
His 44-year-old son David was arrested on a nearby street and later charged with murder.
A Metropolitan Police spokesman said: “Officers and ambulance services attended and found the body of a man, aged 70, believed to have been stabbed. He was pronounced dead at the scene. Next of kin have been informed.”
