A MAJOR EastEnders spoiler has leaked months ahead of airing – with a huge wedding set to take place in Walford this summer.

The BBC soap recently filmed a top secret wedding on the Elstree set and unfortunately for them, parts were captured by drone footage.

The footage was then leaked online by fans – months before airing.

It shows a party in the Queen Vic and a stretched limo arriving in the Square with some of Walford’s finest in their Sunday best getting into the party atmosphere.

A source said: “It’s a bit of a nightmare.

“Drones are always hovering about but this is the first time a major storyline has leaked from them.”

In the video – that has now been removed from the internet – a cast member can be seen beckoning the drone in further while filming in the famous Square.

The wedding is set to air this summer and has been kept a closely-guarded secret – though there are a number of couples that could be tying the knot.

Lauren Branning and Peter Beale were the most recent to get engaged after a family secret confirmed that Lauren hadn’t tried to kill Cindy Beale during a drug-induced blackout.

The recently returned Vicki Fowler and new love Ross could also be a potential summer wedding.

And next week’s spoilers have revealed that Harvey Monroe and Jean Slater are also getting engaged.

However with Harvey’s affair with Kathy Beale set to be exposed – could it be Harvey and Kathy walking down the aisle?

A BBC spokeswoman was contacted for comment.
