Jm Jungle, trained by John and Sean Quinn, was a surprise 14-1 winner of the Group Two King George Stakes on the penultimate day of Glorious Goodwood.

Ridden by Jason Hart, it was the five-year-old’s first outing at Group-race level.

Having broken smartly from the stalls in the far-side group, Hart steered his mount into the lead inside the final furlong and was able to prevail by a neck.

“He’s a very, very good horse,” Sean Quinn – who trains alongside his father John – told ITV Racing. “I’m a little bit lost for words to be honest.”

She’s Quality was runner-up for her fourth race in succession, with Commonwealth Cup winner Time For Sandals half a length further behind in third.

Favourite Big Mojo could only manage a fifth-placed finish.

The final day of Glorious Goodwood takes place on Saturday, when the Stewards’ Cup takes centre stage at 15:05 BST.
