A record 66,000 tickets have been sold for this year's tournament, which runs from December 17 until January 3, and the £1.5m event has been given a further boost with the extension of the William Hill contract.

“I’m delighted that we’ve extended our sponsorship agreement with the PDC for a further five years, as the William Hill World Darts Championship is now one of the highlights of the sporting calendar and one that takes centre-stage over the festive period,” said James Henderson William Hill CEO.
