Ronnie O’Sullivan claimed some referees “have it in for me” as he crashed out of the World Snooker Championship in a 13-10 quarter-final defeat to Stuart Bingham.

Bingham, the 2015 champion, reeled off the last three frames to secure a famous win but it was overshadowed by a bizarre incident in the 12th frame involving O’Sullivan and referee Desislava Bozhilova.
