Baaeed, Nature Strip and Coroebus were the big winners on a thrilling opening day at Royal Ascot.

Australian sprinter Nature Strip surged clear to take the King’s Stand Stakes from Twilight Calls after American rival Golden Pal was slowly away.

Baaeed extended his unbeaten run to eight in the Queen Anne Stakes, while 2,000 Guineas winner Coroebus landed the St James’s Palace Stakes.

The world’s top-rated horse Baaeed got the meeting off to a brilliant start with a classy win in the Queen Anne Stakes.

The 96-year-old monarch has been experiencing mobility problems and did not attend on Tuesday, but may be there on another day, in what is her Platinum Jubilee year.

Nature Strip at 9-4, the first Australian-trained victor at Royal Ascot since Black Caviar in 2012, won by four and a half lengths from Twilight Calls with 200-1 shot Acklam Express and Mooneista close up in third and fourth respectively.
