Belle Dingle's mental health is set to spiral out of control in Emmerdale next week.

Emmerdale spoilers have revealed that The Dingles begin to speculate over the identity of the new witness who’s given evidence against Belle (Eden Taylor- Draper) in upcoming scenes.

Fans of the ITV soap know that Jamie Tate (Alexander Lincoln) mowed down Moira Dingle (Natalie. J Robb) in a hit and run incident in August and the cunning vet has since framed his ex-lover Belle.

Realising she’s behind on her medication, Sam Dingle (James Hooton) encourages Belle to take her pills, but the voice of her late mum Lisa Dingle tells her not to and Belle’s obedient so doesn’t.

Cain Dingle (Jeff Hordley) and Moira see Jamie in the street and confront him but Moira convinces Cain to back-down and leads him away.

She speculates Jamie will likely have left some piece of loose evidence lying around, which they’ll be able to use against him. And soon Cain and Moira break into Home Farm to find it.

Meanwhile, Nate Robinson (Jurell Carter) is stunned to realise the extent of Belle’s history with schizophrenia and realises the gravity of the situation.

When the Dingles realise Jamie has cottoned on to their plan, their situation seems hopeless until Nate offers to take the rap for the hit and run in an effort to keep Belle out of harm’s way.

Cain can’t help admiring his son but they are unaware that Tracy is listening, and she's livid to discover Nate’s thinking of going to prison for Belle.

Arriving at the police station with Cain, Nate struggles to muster the courage to enter the station and confess to the hit and run.

Will he actually take the blame?

Meanwhile Belle’s mental health takes a turn for the worst later in the week.

The voices in her head convince her that all the terrible things happening in her life at the moment are because of Jamie's ex, Andrea, and she therefore needs to be punished.

Will Jamie push Belle over the edge?

Speaking about the difficult storyline, Eden revealed: "Belle's mental health isn't great and it's taken a turn. Nobody is really there to see it happening or prevent it. Belle starts to spiral."

She continued:"At first it's her mum she thinks she can hear Lisa. Belle finds that massively comforting.

"I don't think she really realises that she's ill. Because it's her mum, she just thinks it's great."

She added: "Then her mum says she has to get revenge and that it's all about getting her own back.

"Belle starts to do things that aren't right and that aren't Belle. She doesn't understand why her mum wants her to do those things.

"Because it's her mum, she trusts it and goes with it. That's when it becomes serious."

Will Belle end up going to prison over Moira's hit and run?
