Mike Smith and wife Sarah Green
Former Radio 1 presenter Mike Smith has died in hospital at the age of 59.
The broadcaster had complications connected to his recent major heart surgery.
He was married to fellow television personality Sarah Greene for 25 years.
In a statement released through Smith's aerial filming company Flying TV, Ms Greene said she would "like to offer enormous thanks to the staff at the hospital for their care and compassion".
The statement said Ms Greene has asked that she, her family and friends be allowed to mourn in peace.
A Flying TV spokesman said: "Mike founded Flying TV ten years ago and the company says his legacy will be FTV continuing to go from strength to strength."
The couple were married in 1989 Smith's career began at hospital radio before joining BBC Radio 1 in 1975.
In 1983, Smith took over the weekday lunchtime show and took on the Breakfast Show in 1986, succeeding Mike Read.
Smith was a key figure in the early years of Comic Relief but largely stayed away from the limelight after a helicopter crash which injured both himself and Ms Greene in 1988.
The qualified pilot and his then-girlfriend Ms Greene were injured when the helicopter he was piloting crashed in Gloucestershire.
Both passengers survived, although Ms Greene broke both legs and an arm, and Smith suffered a broken back and ankle.
Smith proposed to Ms Greene just weeks later and they were married the following year.
They were childless and lived in London.
