EASTENDERS fans think someone behind the scenes may be about to lose their job after the soap has accidentally revealed a major spoiler.

Viewers have tuned into the long-running BBC serial drama to watch Zack Hudson’s showdown with members of the Mitchell family.

Although he’s the half-brother of Sharon (Letitia Dean) who has some protection from her ex-husband Phil (Steve McFadden), he’s become embroiled in a major plot.

Zack previously worked as a personal trainer when he had an illicit affair with Nicola (Laura Doddington) behind the back of her husband Teddy (Roland Manookian).

This resulted in the birth of Barney Mitchell (Lewis Bridgeman), who thought Teddy was his father throughout his childhood.

Nicola also let Teddy believe that he was the father as she kept the secret completely hidden, until Zack recently found out the truth.

Teddy tried to stop his other son Harry (Elijah Holloway) from killing him, only for the pair to be involved in a huge car crash.

Zack’s fate hung in the balance and he was initially feared to be dead after the vehicle plunged into a lake.

The soap’s official social media accounts were all meant to post a behind the scenes video of the car stunt.

However, producers behind the scenes seemed to accidentally post a major spoiler video of next week’s events instead.

In a massive blunder, Zack is revealed to be alive as he dramatically walked into his house looking completely dishevelled.

Vicki Fowler (Alice Haig) and Linda Carter (Kellie Bright) were utterly relieved when he sensationally re-entered number 43.

He later claimed that he got away as he swam to the other side of the lake to get out of reach of the Mitchell’s, whom he realised tried to kill him.

As the video went viral on social media, longtime EastEnders fans were left scrambling by the blunder.

On social media fan-forum site Reddit, one viewer wrote: “So on YouTube there’s a video which is meant to be BTS of the car crash but it’s actually the weekly recap and yeah… …spoilers.”

Fans flooded the post with comments as someone joked: “Someone is going to be fired.”

A third user said: “I swear the person in charge of socials is about to have the passwords changed on them! Is this not the second mess in the space of a week?”

“Oh my god I work in a similar field (we’re not all interns haha) and this is the stuff of nightmares. Hopefully they manage to get it sorted and have procedures in place to avoid it again!”, explained someone else.

And a fifth added: “Someone is so getting fired.”

This comes after the soap accidently leaked a huge spoiler about the Queen Vic, months before it was due to be shown on screen.

In a post uploaded to the official TikTok account, fans noticed that a for sale/auction sign had been placed on the side of the Queen Vic.

This suggested that the current owners Linda Carter and the Knight family are set to lose the pub in a shock new storyline.
