Bushby said he swam for 20 hours over three days, making landfall at Shakespeare beach, just south of Dover, at 15:30 BST on Monday.
Bushby’s team said he was welcomed on the beach by a small gathering of friends and family, including his father, Keith Bushby, a former SAS soldier, and acclaimed filmmaker Werner Herzog, who is directing a feature-length documentary about the journey titled Walk of Life.

However, Bushby’s team said permission had been sought from both French and UK authorities, and said they chose not to publicise exactly when it would take place “for safety and security reasons”.
