Emmerdale spoilers: Wallop! Gentle Sam Dingle punches hardman brother Cain

Sam lashes out at Cain in the Woolpack, Emmerdale. .

Emmerdale's Sam Dingle punches Cain in Monday's episode (ITV, 7.30pm, see our TV Guide for full listings).

War has been raging between Sam Dingle's immediate family and his brother Cain's.

The root cause is Samson, Sam's son who claims Cain's stepson Matty stabbed him in the Hide.

Most know that Matty is as gentle as they come and would never do such a thing, and they rightly suspect Samson is covering for his aggy mate Josh.

Samson's denied it and his dad Sam and stepmum Lydia have backed him.

But Lydia's recently found out that the teenager has been lying after all and is sickened.

While Sam wants his lad to do a runner to escape a brush with the law, Lydia's insisting he tell the police the truth.

When Lydia manages to get her way, Sam is utterly furious with his wife.

Sticking to her guns, Lydia then braves Moira, whose son Matty is going through hell in prison trying to hide the fact that he's a transgender man (which is how the problem with Josh started in the first place).

Moira's relieved to hear the truth is out and dares to hope Matty may soon be home safe and sound.

But Sam's at boiling point and after bursting into the Woolpack he lamps his judgey brother Cain!
