| The Queen with her daughter Princess Royal welcoming Estimate after the Ascot Gold Cup |
Estimate, Queen Elizabeth’s Ascot Gold Cup winner, has tested positive for the banned substance morphine, Buckingham Palace announced. The shocking development follows news late last week that traces of morphine had been found in samples provided by five horses, Estimate among them.
Apparently, it is thought the positive drug tests may have been a consequence of eating contaminated feed.
