Emotion overflowed for Frankie Dettori as he celebrated another magnificent milestone by clinching a 50th Royal Ascot winner with a last-gasp success aboard Osaila in the Sandringham Handicap.

Time Test looked a much improved performer when winning a handicap on his return at Newbury, and can make the successful step up to Group company in this afternoon’s Tercentenary Stakes at Royal Ascot.

Derby winner Australia, Leading Light, The Grey Gatsby, Gleneagles, Tapestry and Chicquitaheads a star-studded list of entries for the inaugural Irish Champions Weekend at Leopardstown on Saturday and the Curragh on Sunday.

Frankie Dettori has lost the ride on Prix de l’Arc de Triomphe winner Treve and will be replaced by Thierry Jarnet in the Prix Vermeille on Sunday, at the request of trainer Criquette Head-Maarek.
