The Diplomat, Netflix’s smash-hit political thriller series, has a stacked cast – here’s a full rundown of the actors and the characters they play.

Created by Debora Cahn, a writer-producer known for her work on The West Wing and Homeland, The Diplomat has been faring well with critics and audiences alike – it’s currently number one on Netflix’s top 10 TV shows chart.

The plot centers on a US ambassador to the UK as she battles forces at home and abroad, whether it’s the threat of war bubbling away in the Persian Gulf, international alliances cracking at the seams, or her marriage to the former ambassador.

While The Diplomat has since left the Netflix chart, here’s all the characters you need to know in the show’s cast.
