His main rivals in the betting were the British filly Dunfermline, who had inflicted Alleged's only defeat in the St Leger Stakes, the Prix du Jockey Club winner Crystal Palace, the four-year-old Crow, and the five-year-old Orange Bay.
The international entry included the New Zealand-bred, British-trained Balmerino, Mia from Argentina, Cunning Trick from the United States and Vivi from Germany.
[1] Piggott sent Alleged into the lead from the start and set a steady pace with Crystal Palace, Crow and Orange Bay close behind.
With no designated pacemakers and none of the recognised stayers making any attempt to challenge for the lead, the Irish colt was allowed to dictate the pace and on the downhill run towards the turn into the straight he led from Crystal Palace, Crow, Montcontour, Orange Bay and Yelpana.
Although several horses made progress in the closing stages, Alleged was never seriously challenged and won by one and a half lengths from Balmerino, with Crystal Palace taking third, just ahead of Dunfermline and Crow.
