Celebrity Traitors plunged into chaos after finale leaks online hours before it airs on TV

The reality series has been the most-watched show of the year, quickly surpassing all previous seasons in terms of rankings.

Tonight’s finale will determine whether traitors Cat Burns and Alan Carr can outmatch the faithful and win the prize fund of up to £100,000 for their chosen charities.

But, with just one episode remaining, the series was plunged into chaos.

With just hours to go until the highly anticipated finale airs on TV, fans noticed it had already been uploaded by Canadian streaming site Crave and was available for anyone to watch online.

While we won’t spoil the ending here, one fan who watched the episode told The Sun: “I have been watching Celebrity Traitors through Crave all season long.

"Having not realised that the finale was airing tomorrow [in the UK], I logged on this afternoon and found it available.

“It was only brought to my attention part-way through by a friend outside of Canada that the finale isn’t scheduled to air tomorrow [Thurs in the UK].”

Another fan added: “It was really good.”

Viewers in New Zealand have also had the chance to watch the episode early via ThreeNow, the streaming site for Channel 3.

The episode was taken down after 90 minutes, but hundreds of fans had already watched the big finale at that point.

The BBC is yet to comment on the leak.
