Paris, France (AFP) — Aidan O’Brien has said some people might think him “weird” as he finds holidays “stressful” but for his wife Anne-Marie, he is the most successful racing trainer in the world because “he puts everything he has into what he does”.

The 56-year-old Irishman’s efforts have been rewarded with a whole host of landmarks including a record 12 Epsom Derbies and in 2017 the most Group/Grade One wins in a season.

Another one can come his way this week as he needs just four winners to become the first trainer to bring up the century mark at Royal Ascot.
