2023 St Leger Odds - Arrest the new favourite after Dettori u-turn

Let's take a look through the latest St Leger betting and run through the headline entries.

Following victory in the Queen's Vase at Royal Ascot, Gregory shot to the head of the St Leger betting. John and Thady Gosden's colt finished a disappointing third after attempting to make all in the Great Voltigeur Stakes at York last time out, but Gregory still remained the favourite for the St Leger.

That was until Thursday afternoon, when it was confirmed that Frankie Dettori was switching his allegiance to Arrest. The Chester Vase winner will relish the ground conditions at Doncaster on Saturday and Arrest has been backed into 3/1 favouritism for Saturday's main event.

Great Voltigeur winner, Continuous now sits second in the market, following his impressive victory on the Knavesmire. Continuous will be joined in the field at Doncaster by Tower Of London, Denmark and Alexandroupolis.

Qatar Racing will be represented by Roaring Lion colt Middle Earth, who was supplemented after an impressive win in the Melrose Handicap at York. Third in the betting is the Royal runner, Desert Hero, who built on an impressive handicap win at Ascot by scoring in the Gordon Stakes at Glorious Goodwood. Simon & Ed Crisford's Chesspiece could fly the flag for Godolphin in the final Classic of the season.
