With One Direction releasing their last video before their break, William Hill are offering just 1/3 that it reaches one billion views on YouTube before the end of the year (9/4 it does not).

“This is the boys’ farewell to the fans and there will be plenty of heartbroken Directioners who will be rewatching this video over the course of the year to remember the good times,” said William Hill spokesman Joe Crilly.

One face who, perhaps surprisingly, features in the video, is Zayn Malik. His new single is released on Friday and is 4/6 to head straight to the top of the charts.

“Zayn’s departure may well have been the catalyst for the hiatus, however, we think his fanbase remains strong enough for his single to bag the UK number one,” said William Hill spokesman Joe Crilly.
