Ronnie O’Sullivan's chase for a record eighth World Championship is over after defeat to Stuart Bingham on a day of drama at the Crucible. The 48-year-old had hoped to move clear of Stephen Hendry as the most successful player at the event in the modern era, but exited at the quarter-final stage after a chaotic encounter that ended 13-10 in Bingham’s favour. Bozhilova, 31, has refereed on the professional tour for 12 years.
