Michael Jarvis, one of the longest-serving trainers in Newmarket, has been forced to retirement due to medical advice.
The 72-year-old has undergone heart surgery and treatment for prostate cancer recently and has been absent from the racecourse in recent seasons.
His assistant, Roger Varian, will take over the reins at Kremlin House, hopefully in time for the new Turf season.
Jarvis will be best remembered for his multiple Group One winner Rakti, 1989 Prix de l’Arc de Triomphe hero Carroll House and Classic winners Ameerat and Eswarah.
Jarvis has held a licence for 43 years having had a short spell as a jump jockey.
He was head groom to Towser Gosden and Gordon Smyth before taking out a licence in 1968.
Fellow trainers were quick to make their appreciation of Jarvis known on the social networking website Twitter.
Ed Dunlop, who also trainers at Headquarters, said: “Just read the very sad news that Michael Jarvis has announced his retirement, one of my heroes, a true gent and a great trainer.
“(I) also would like to wish Roger, his assistant, best of luck with the yard, I’m sure he will do very well.”
While Roger Charlton added: “Very sorry to read that Michael Jarvis is to retire from training. I have the greatest respect for him, polite, clever, successful and kind.”
