Ghaiyyath took his brilliant winning run to three Group Ones this season by repelling all challengers in the Juddmonte International Stakes at York.
Charlie Appleby's front-runner led throughout once again as he saw off a top-class five-strong field to win by three lengths as the 11-8 favourite, under William Buick.
Ghaiyyath predictably had to contend with the close attendance of outsider Rose Of Kildare in the early stages - and once that hazard was out of the way, he was harried into the final two furlongs by 2000 Guineas winner Kameko and multiple Group One heroine Magical.
But none ever closed within two lengths as Appleby's five-year-old added this success to his Coronation Cup and Coral-Eclipse victories in the past two months.
Magical took second spot, with Lord North eventually staying on past Kameko into third.
Appleby said: "I'm delighted with that. It was straightforward, a great performance and a great front-running ride by William.
"Most importantly, it's important for His Highness Sheikh Mohammed and the team to have a horse like this on our hands.
"He's not let us down this year and as I said right at the start of the year, he's more the finished article now. I'm just delighted for the whole team."
