Oswald Mosley's Fate in Peaky Blinders Oswald Mosley, the chilling fascist leader introduced in Season 5, becomes a central antagonist for Tommy Shelby across Seasons 5 and 6. Played by Sam Claflin, his character draws from the real-life British Union of Fascists founder, amplifying the show's pre-WWII tensions. Tommy's intricate schemes against him drive much of the final season's drama.

Season 5 Introduction

Mosley first clashes with the Peaky Blinders at a high-society party hosted by Tommy.

  • He reveals knowing Lizzie from her past as a prostitute, using it to unsettle her and probe Tommy's vulnerabilities.
  • Mosley pitches his British Union of Fascists (BUF), rallying aristocrats and positioning himself as a rising political threat with ties to global fascists.
  • Tommy, playing a double game as an MP, secretly plots his assassination while pretending alliance—setting up the razor-sharp intrigue that defines their rivalry.

This encounter marks Mosley as untouchable at first, his charisma and connections making him a formidable foe beyond street-level gangsters.

Season 6 Escalation and Assassination Attempt

By 1933-1934, Mosley's influence peaks amid economic despair, mirroring real 1930s fascism.

  • Tommy allies with the IRA for a public hit during Mosley's BUF rally speech, recruiting sniper Barney Thomason to shoot from the rafters while Tommy distracts on stage.
  • Chaos erupts: IRA informant Laura McKee's betrayal (orchestrated by Mosley's circle) triggers a premature gunshot, allowing Mosley to escape unharmed in the nick of seconds.

"Unfortunately, the assassination does not go as planned, and Mosley is able to escape alive."

Post-attempt, Mosley tightens his grip:

  • He meets Benito Mussolini and Adolf Hitler, even hosting the latter at his wedding, underscoring his real-world fascist links fictionalized for tension.
  • With lover Diana Mitford and US gangster Jack Nelson, Mosley pressures Tommy—his doctor fakes a terminal tuberculoma diagnosis to push Tommy toward suicide.
  • This scheme shatters Tommy's marriage after Diana sleeps with him, sparking Lizzie's fury.

What Ultimately Happens to Mosley?

Tommy never gets direct revenge.

  • The failed plot leaves Mosley unscathed; he continues building BUF power as Season 6 closes in 1934.
  • No on-screen death or arrest occurs—Mosley "walks away untouched," reflecting historical survival into WWII (he was detained in 1940 but released later).
  • Fans debate this open ending: some call it realistic (Mosley died naturally in 1980 at 84), others wish for poetic justice in the upcoming Peaky Blinders movie.

Fan Reactions and Trending Discussions

Recent forums buzz with frustration over Mosley's "buffed" invincibility—portrayed as too powerful versus the real street-gang Peaky Blinders.

  • Reddit threads question why Tommy spares him, speculating movie closure amid WWII focus.
  • As of March 2026, no new series resolves it, but the movie (in development) might revisit fascism's toll on the Shelbys.

From multiple viewpoints: Purists appreciate historical fidelity (Mosley thrived until internment), while viewers crave vigilante payoff. This ambiguity fuels endless "what if" debates, blending gritty storytelling with realpolitik dread.

TL;DR : Mosley survives Tommy's failed assassination in Season 6, evading revenge and rising in fascist influence—leaving his arc open for potential movie exploration.
