Intro:

Camelot, the 13-8-on favourite ridden by Joseph O'Brien for his father Aidan, galloped to a dazzling five-length triumph in the Epsom Derby on Saturday.

Among the 150-thousand spectators at Epsom on Saturday - a very special visitor ...

British Queen Elizabeth II chose the Derby to launch the four-day Diamond Jubilee celebrating her 60 years on the throne.

Always a massive fan of the turf, the Queen will not have witnessed many races as significant as this.

Astrology made much of the going in the nine-horse field - the smallest for the race since 1907.

But come the closing furlongs, Camelot showed why he was the favourite with the bookmakers.

Ridden by Joseph O'Brien for his father Aidan, Camelot galloped to a dazzling five-length triumph.

It was a third winner of the big race for Irish trainer Aidan and a first for his 19-year-old son.

No father-son combination had ever won the mile-and-a-half race.

Ted Durcan's mount Main Sequence made late ground to take second place with O'Brien's Astrology.

O'Brien senior won the Epsom Oaks on Friday with 20-1 shot Was.

He also captured the first two classics of the season, the 2,000 Guineas, via Camelot - and the 1,000 Guineas, through Homecoming Queen.
