The Diplomat cast: who's who in the political thriller series

The Diplomat cast: Keri Russell as Kate Wyler

The Diplomat is a new thriller series with a great cast, centered around career diplomat Katherine Wyler, who lands the job of US ambassador to the UK.

It's no easy job, especially as threats of war continue to bubble over across the world, forcing Kate to diffuse international crises, forge strategic alliances, and adjust to her new life in the UK, while also dealing with conflicts in her own marriage to a fellow diplomat.

The Diplomat showrunner Debora Cahn has worked on Homeland and The West Wing so she's no stranger to the thrilling world of global politics, and she's assembled a great cast for the new series.

So who's in The Diplomat? Here's everything you need to know...
