If you watched Netflix's enthralling show The Crown, you're probably aware Queen Elizabeth II has had a lifelong passion for horses.

At the age of 91, she still occasionally enjoys a morning horse ride; the Racing Postis one of her favourite daily newspapers, which she avidly reads in the morning over breakfast; and naturally, she knows a thing or two about horse breeding and horse races, which she attends regularly.

Now, figures sent by the Blueclaw agency show Her Majesty earned over £6.7 million ($8.8 million) in prize money from racing her horses in the past 30 years.

Since 1988, the Queen won 451 races with her best year being 2016, where she earned £557,650.

Her Majesty is currently 11th in the flat Owners' Championship, with 20 races won and total earning of £413,641 so far.

Her most successful horse is Merlin, who has won 3 out of 8 runs and earned a total of £21,768.

If we look at the winning percentage, the Queen's most successful horse is Elector, who has a 100% race win record. Elector is followed by Daphne and Elementary, who both have 50% race win.

"The next horse owned by The Queen that is due to race is Patchwork, trained by Richard Hughes in the 32 Red Handicap at Kempton," Blueclaw reports.
