Emmerdale airs trouble for Chas Dingle later this month as Belle catches her out in more lies.
Chas was rumbled by Belle in the early stages of her affair with Al Chapman in August. She secured Belle's silence by promising to end things with Al, but she continued the fling in secret.
In recent weeks, Chas' world has been turned upside-down after Al was shot dead.
Chas has struggled to move on from her love for Al, but upcoming episodes see her attitude start to change as she focuses her attention on her family again.

Chas shares a touching moment with her husband Paddy and their daughter Eve when they decorate the Christmas tree together.
A family dinner with Rhona Goskirk and Marlon Dingle then leaves Chas more grateful for Paddy and Eve than ever before.
Unfortunately for Chas, just when it looks like she is ready to put Al in the past, Belle becomes suspicious over the recent events that have rocked the Dingle family.
Chloe Harris speaks to Belle about her recent research into Al's affair. She mentions that Al took someone out to dinner on the night that Faith died.

The penny drops for Belle, as she realises that Chas didn't end her affair with Al.
Belle wastes little time before confronting Chas, revealing that she knows Chas and Al were at a hotel together when Faith passed away.
Chas realises the game is up and is unable to deny Belle's accusations.
Belle then suggests that this is why Cain killed Al in October, unaware that Cain's son Kyle Winchester was the real culprit.

As Belle realises the implications of Chas' behaviour, Chas fears that it's only a matter of time before she tells the rest of the family.
This worry proves to be well-founded, as Belle breaks down in front of Cain's wife Moira Dingle and shares everything she knows.
Moira is furious as it becomes clear that Chas' affair started the devastating chain of events that led to Al's death and Cain's imprisonment.
The following day, Chas prepares for a romantic trip away with Paddy – but with two members of the family angry with her, will it really go to plan?
Emmerdale airs on weeknights at 7.30pm on ITV1, and streams on ITVX.
