EMMERDALE has left fans in shock after revealing the bombshell identity of Caleb Miligan in an explosive twist.
The businessman - who is played by actor William Ash in the ITV soap - arrived in the village on Christmas Day after tracking down his sibling Chas Dingle at their mother Faith’s graveside.
Fans had always found it strange at why Caleb arrived in the graveyard to find Chas - but in tonight’s episode he admitted he wasn’t looking for her, he was searching for his dad’s grave.
In a shocking twist he revealed himself as Emmerdale legend Frank Tate’s secret son - and that wasn’t all.
Caleb was also revealed to be Nicky’s dad - with the pair working together to bring down Kim Tate and take back their birthright of Home Farm.
Long-time viewers know that Kim watched Frank die after she returned to the village to claim her son Jamie after faking her death to escape Frank.

He suffered a heart attack during a tense confrontation and Kim stopped him from calling for help and watched him die.
After confirming his death with her mirror to check his breath, she fixed her makeup and left his body to be found by his children.
Now Caleb is in the village wanting revenge and has teamed up with his son Nicky to take Kim’s millions.
The shock twist was revealed tonight when Caleb caught Nicky about to attack Leyla Harding - out of defence of Caleb’s wife and his mum.

And Nicky admitted his entire seduction of Gabby is all for his dad’s plan and being with her makes him sick.
Caleb actor William Ash has revealed how he kept the bombshell twist a secret - even from his own on-screen son.
He said: “It’s nice to have their big secret out in the open.
“There’s been a lot of people speculating, even people coming up to me in the street and asking: ‘What’s Caleb up to?’ and ‘why is he in the village?’
“It’s good for that part of the story to be out there, great for the audience so they don’t start losing interest in that thread.”
He added: “I did! I knew that Frank Tate was Caleb’s dad and Faith his mum.
“Plus I knew that Caleb’s son had got a job at Home Farm which Caleb had pushed him to do to place him in that world to find out as much as possible about it.”
William also teased the fireworks to come with Caleb and Nicky being half Tate, half Dingle.
