Manx Grand Prix organisers have confirmed that rider Ian Bainbridge died in the incident that saw Tuesday evening's qualifying session red flagged.
A statement said: 'The organisers of the Manx Grand Prix are saddened to confirm that Ian Bainbridge, 69, from Barnard Castle, was killed in an accident during the second qualifying session for the 2023 event.
'The accident occurred on the exit of Kirk Michael village on his first lap of the session.
'Ian made his Mountain Course debut in 2005 and had been a regular competitor in the classic racing classes ever since, only missing the Manx Grand Prix on two occasions in that time.
