It is run at Newbury over a distance of 7 furlongs (1,408 metres), and it is scheduled to take place each year in August.
The event was originally named after Washington Singer (1866–1934), a prominent racehorse owner and philanthropist.
It has been won by several subsequent Classic winners, including Rodrigo de Triano, Lammtarra and Haafhd.
The race is currently restricted to horses which have not won at Group level, and whose sires achieved victory at distances in excess of 1 mile and 1½ furlongs, or 1,900 metres.
The race title formally changed to the Denford Stakes from the 2017 running.
