Shirley brandishes a gun at Phil and Sharon in EastEnders! (PHOTOS)

EastEnders is set for yet another dramatic wedding as Shirley Carter confronts Phil Mitchell and Sharon Rickman with a gun on their big day.

The couple are due to get married, but Phil (Steve McFadden) has been having an affair with old flame Shirley (Linda Henry), who will be pushed to breaking point by the time the wedding day arrives and is seen in new preview pictures brandishing a gun.

The firearm is actually the same one that Sharon (Letitia Dean) has been hiding for Phil’s cousin Ronnie Mitchell (Samantha Womack), but it finds its way into Shirley’s hands as she turns up in a furious mood at the couple’s home, while they’re dressed in their wedding clothes.

A source told the Daily Mirror: “The gun ends up in Shirley’s hands, but who fires it?”

Sharon has also been keeping secrets from her fiance – she has been stealing from him ever since she found out that he was behind the attack at her bar The Albert, which landed her in hospital.

In a preview of the episode, Phil and Sharon are shown dressed in their wedding clothes and arguing as Phil complains that Sharon has betrayed him, before she hits back: “What do you know about trust?… This is where it ends.”

Will the wedding go ahead?
