Sidecar driver Ian Bell and rider Andrew Soar have become the third and fourth fatalities of this year's Isle of Man TT race following two accidents on Friday.
Bell, 58, was competing with his son Carl, who was reported to be uninjured, according to organisers.
Bell was married to Trudi and had two children.
The British driver had made his debut in the race in 1995 and had achieved five podium finishes, including victory in 2004.
Bell was the third fatality of the event after two competitors have lost their lives during the opening day of the event.
Soar, 32, was also killed today following an accident at Keppel Gate during today's Senior TT race.
Soar had made his first appearance at the TT in 2015.
