Buckingham Palace have announced that the racehorse Estimate owned by the Queen has tested positive for the prohibited substance morphine.
The drug morphine is not prohibited during training but it is banned on race days and the five year old filly Estimate has failed a drugs test after testing positive for the substance.
Estimate who is owned by the Queen is currently being trained by Sir Michael Stoute, this is the same racehorse who raced to glory in 2013 by winning the Gold Cup at Royal Ascot and came second at the annual event this year.
The Queen's racing advisor believes that initial indications are that the positive result for Morphine stemmed from the consumption of a contaminated feed product.
The Queen has been notified of the current events after watching her horse race to success at Royal Ascot last year, she is being kept informed of upcoming developments involving the situation with the ban.
John Warren who is the Queen's Bloodstock and Racing Advisor released a statement regarding the matter: "On Thursday July 17 the British Horseracing Authority (BHA) announced that a number of post-race samples, obtained from recent race meetings, had been found to indicate the presence of morphine, which is a prohibited substance on race days. Five horses, under the care of various trainers, were affected."
He continued to say: "I can confirm that one of those horses was Estimate, the five year-old filly trained by Sir Michael Stoute and owned by The Queen. Initial indications are that the positive test resulted from the consumption of a contaminated feed product."
"Sir Michael is working closely with the feed company involved to discover how the product may have become contaminated prior to delivery to his stables."
Estimate made sporting history for the Queen last year when she became the first reigning monarch to win Royal Ascot's Gold Cup, the Queen proudly watched and cheered as her horse came in for victory and the whole Royal Box celebrated with her.
At the time of the win,Sir Michael said the Queen greatly appreciated the victory: ''It's a special thrill to win this race for the Queen and it will have given her enormous pleasure - she really loves this game and it's a great recreation for her."
