When Camelot stormed home to win the 2012 Epsom Derby it was a performance fit to serve before the Queen on Diamond Jubilee weekend – and a great day for punters as the bookmakers took a bashing.

It was a fairytale result for trainer Aidan O’Brien. The 8-13 shot was  ridden by his 19-year-old son Joseph making the O’Briens the first father-son trainer-jockey combination to win the world’s most important race.

Camelot is now favourite to win the St Leger and become the first horse since Nijinsky 42 years ago to win the Triple crown.

Camelot, already winner of the 2000 Guineas,  surged late for an easy win over Main Sequence and Astrology.

Nijinsky was the last horse to make a clean sweep of the 2000 Guineas, Derby and St Leger in 1970.
