Defending Queen Elizabeth II Cup champion Viva Pataca will be racing for Olympic glory on Sunday. Angela Leong On-kei, fourth wife of owner Stanley Ho Hung-sun, said yesterday her husband's high-class stayer would do his part for the equestrian branch of the Olympic movement as he attempts to run down the fifth Group One race in an illustrious career. 'We have committed that the owner's share of any prize money we win in Sunday's race will be donated to the Equestrian Federation for the Olympics,' Leong (pictured) said. 'The people of Hong Kong are so excited about the equestrian competition and I know it will bring great glory not only to Hong Kong, but to China as well. 'Dr Ho is making donations all the time to what he considers worthy causes and he sees the equestrian competition of these Olympics as very important. Viva Pataca is a great horse and through him we hope we can do something positive to make a contribution to the success of the coming Olympics.' The $14 million sponsored Cup race is worth $8 million to the winner.
