Netflix has renewed its hit political thriller The Diplomat for a fourth season, ahead of the release of its third.
The news comes as a surprise, with season three of the Keri Russell-led series not expected until late 2025.
The streaming giant made the announcement earlier this week, confirming the next chapter in Kate Wyler’s story is already in development.
The series follows Kate, the US ambassador to the UK, as she navigates the demands of diplomacy while dealing with her troubled marriage to fellow political operative Hal, played by Rufus Sewell.
A double dose of drama on the way

Praised for its sharp writing, tense plotlines and standout performances, the show was hailed as one of the best dramas of the decade.
Season two continued the momentum, ending on a dramatic cliffhanger that left viewers demanding answers.
Now, with season three still in post-production, fans are already looking ahead to season four.
Showrunner Debora Cahn hinted at even bigger twists to come: “Season three flips the chessboard. Kate lives the particular nightmare that is getting what you want.”
