Police experts found forensic evidence from Al Saud on Mr Abdulaziz’s underwear. Despite this, the prince continued to deny he was gay.
But Mr Laidlaw said: ‘The evidence establishes quite conclusively that he is either gay or that he has homosexual tendencies.
‘There is clear evidence, over and above the bite marks, that there was also a sexual element to his mistreatment of the victim.’
A search of the prince’s laptop revealed he looked at gay massage and escort agency websites, jurors were told.
