Olympic parachutist Mark Sutton's reportedly fatal accident is understood to have happened on the first day of a three-day wingsuit event near Martigny, in the Valais canton, near the French border.

A video on Mr Sutton's YouTube account shows him in several wingsuit flights, including this one near Riva del Garda in northern Italy in August last year, which he introduces with a reference to Team GB:
