Ronnie O'Sullivan beat Ali Carter 18-11 to secure his fourth World Championship title at the Crucible.

Having started yesterday 10-7 ahead, O'Sullivan took the first four frames, reeling off his 12th century of the tournament in the process.

Carter looked a beaten man but rallied to win three frames in a row and take the match into a final session.

But Carter won only one more frame as O’Sullivan wrapped up proceedings in a little under an hour.

O'Sullivan was delighted to share his triumph with his young son, Ronnie Jr, who joined his dad in the arena after victory had been clinched.

"It was the best. I didn't think I'd ever get the opportunity to share those moments with him so it was so nice to have him here," said the 36-year-old.

"I got a bit emotional before the match was over, it felt like just me and him in the whole arena. There was just this massive connection between me and him, the best feeling I've ever had in my life."
