The ex-husband of Stagecoach millionaire Ann Gloag has died after his car left the road and crashed into a field in Perth.
Ann Gloag was sorry to hear of her ex-husband's "sudden tragic death"
Tayside Police said Robin Gloag, 64, from Inchture, was killed on Low Carse Road - near his home town - just before 2100 GMT on Wednesday.
His overturned silver Renault Laguna was spotted close to a farm by a passing motorist, who raised the alarm.
Emergency services were called but Mr Gloag was pronounced dead at the scene.
Mr Gloag helped set up the bus company Stagecoach in the early 1980s before leaving the company. The couple later divorced.
The former bus driver then set up Highwayman coaches.
In a statement, Ann Gloag said: "I'm very sorry to hear of his sudden tragic death."
A member of Mr Gloag's family, speaking from his home, was too upset to comment.
Tayside Police said no other cars were involved in the incident and officers have appealed for witnesses to come forward.
The road remains closed and enquiries have been continuing.
In 1999, Robin and Ann Gloag's son Jonathan, 28, was found dead in woodland in Perthshire.
Jonathan was married to Sarah, the daughter of her second husband David McCleary.
Ann Gloag and her brother, Brian Souter, became Scotland's most famous entrepreneurial duo after building Stagecoach from a one bus operation into a transport empire spanning four continents.
The firm was floated on the stock market in 1993, making Ms Gloag a multi-millionaire.
