Marwan Koukash is a businessman and racehorse owner whose horses have won races including the Critérium de Maisons-Laffitte, Cesarewitch Handicap, City and Suburban Handicap, Ayr Gold Cup and Chester Cup.

The City and Suburban Handicap is a flat handicap horse race in Great Britain open to horses aged four years or older. It is run over a distance of 1 mile 2 furlongs and 17 yards at Epsom in April during the Epsom Spring meeting. Inaugurated in 1851 it originally attracted top-class racehorses in the 19th and early 20th century; today its importance has been eclipsed by larger stakes races with more valuable purses.
