Michael Gray goes from trusted Shelby family member to full-blown traitor, and he’s ultimately executed by Tommy Shelby after a failed attempt to kill him.

Quick Scoop: What Happens to Michael Gray?

  • Michael is introduced as Polly Gray’s long-lost son and becomes a key player in the Peaky Blinders business.
  • Over time, he grows ambitious, clashes with Tommy, and starts believing he should be the one running the organization, especially after his stint in America.
  • He proposes a plan for the American side of the business that would effectively sideline Tommy, which Tommy rejects, creating a deep rift between them.
  • After Polly is killed (in the fallout of Tommy’s war with his enemies), Michael blames Tommy completely and becomes obsessed with revenge.
  • By season 6, Michael is effectively positioned as Tommy’s “enemy” within the family, plotting to destroy him.

Betrayal, Prison, and Revenge Plot

  • Michael gets involved with the American mob and uses those connections to try to push Tommy out of power.
  • His earlier actions and shady dealings land him in prison for a time, which further fuels his anger at Tommy, as he believes Tommy failed him and his mother.
  • From behind bars and later on release, he works on a plan to assassinate Tommy, treating it as both a power move and an act of vengeance for Polly.

How Michael Tries to Kill Tommy

  • Michael’s big move is a car-bomb plot: he plans to blow up Tommy by having him enter a car rigged with explosives.
  • He believes he has outplayed Tommy and that once Tommy is dead, he’ll be able to reshape the business and avenge Polly.
  • What Michael doesn’t realise is that Tommy has anticipated the betrayal and has the explosives switched to another vehicle.
  • The bomb goes off, killing Michael’s associates instead of Tommy, and the whole plan collapses in an instant.

Michael’s Death

  • After the failed bombing, Michael and Tommy finally confront each other face to face.
  • Michael, still burning with hatred, throws final accusations at Tommy about Polly’s death and insists that anyone close to Tommy is doomed.
  • Tommy, unmoved, tells Michael that Polly used to visit him in his dreams but will not anymore, a chilling emotional beat that underlines how far things have fallen.
  • Tommy then shoots Michael in the head, killing him on the spot and ending his arc as a “protagonist turned final antagonist.”
