‘Doctor Who’ Reunion Is Officially Happening in Steven Moffat’s New 6-Part Series

More than a decade after Doctor Who bid farewell to Clara Oswald, Jenna Coleman and former showrunner Steven Moffat are finally set for a reunion. Moffat, who stepped down from the show in 2017 and was the powerhouse behind the Benedict Cumberbatch-led Sherlock, will take on the entirely new world of politics and government in the upcoming Channel 4 comedy-drama Number 10. Coleman will appear as one of the three leads in the six-episode series, following a much-lauded turn as Queen Victoria in the Masterpiece-ITV miniseries Victoria and playing the recurring role of Johanna Constantine in Netflix’s The Sandman until it ended last year.

Coleman’s time as Clara Oswald is known for bringing about one of the most complex evolutions of a companion in modern Doctor Who history; Moffat originally developed her “impossible girl” character as a mystery box plot device, appearing across eras and timelines to create a narrative puzzle, and giving her a playful, surface-level personality. The regeneration of the Twelfth Doctor (Peter Capaldi) saw Clara grow into a bold, assertive partner, ultimately becoming a mirror image of the Doctor ​​​​​​and continually toeing the line between deep affection and wanting to be a Time Lord herself. Coleman’s eventual exit led to “Hell Bent,” one of the show’s most cinematic, devastating, and divisive episodes, which eschewed the traditional blockbuster finale in favor of emotionally raw character study to conclude her arc.

Number 10 is set within the real-world residence and office of Britain’s Prime Minister, 10 Downing Street, depicting the inner workings of government and the chaotic lives of those within the storied address. The regime in power is fictional, the party it hails from is unspecified, and it’s billed as the furthest thing from a political thriller focused on a world-ending threat. Instead, it’s a workplace comedy-drama built around the very real problems – global and domestic, interpersonal and romantic – faced within the walls of the terraced townhouses where a country is run from a brick-lined street.

The Doctor Who reunion sees Coleman as Katie Flynn, Deputy Chief of Staff, alongside fellow Whoniverse alum Katherine Kelly, who played a physics teacher in the Moffat-produced spin-off Class but now appears as Chief of Staff Frances Telford. Rounding out top billing is Trying star Rafe Spall as Prime Minister Harry Douglas; they’re joined by a sprawling ensemble supporting cast whose roles have been kept under wraps, but includes Laura Haddock, Akshay Khanna, and Robyn Cara. It’s the first project Moffat has written for Channel 4, and it’s produced by Hartswood Films, the independent production company led by his wife, producer and CEO Sue Vertue, where he serves as creative director.

‘Number 10’ Looks To Be the British Version of ‘The West Wing’

While the title of greatest political show ever unquestionably belongs to The West Wing, the two shows that trail closely behind it got their start in the UK. Building off the legacy set by iconic 1980s satires Yes Minister and Yes, Prime Minister, Armando Iannucci’s scathing, often NSFW mockumentary The Thick of It starred Doctor Who‘s Peter Capaldi, counted Succession creator Jesse Armstrong among its writers, and eventually served as the basis for HBO’s award-winning Veep. And then there’s House of Cards, the four-part miniseries often cited as one of the best in UK history, which walked the halls of the Commons years before David Fincher‘s took it stateside for the Netflix adaptation that forever changed the television landscape.

Moffat, who was quoted in 2023 as saying he wanted to write the British version of The West Wing and thought it “necessary” for the times, is now uniquely poised to deliver. The Doctor Who reunion should come as no surprise; Clara began as a one-dimensional character, but over the course of four years, Moffat’s writing and Coleman’s acting evolved her into a deeply complex companion whose tenure now ranks as the longest in modern Doctor Who history. While there’s no concrete release date yet for Number 10, Moffat and Vertue noted filming had recently wrapped during an interview at Series Mania in March, so all eyes are on the Channel 4 schedule for later this year. Suffice it to say, if Moffat’s past work is anything to go by, it’ll be well worth the wait — and if there’s anyone with a strong enough cultural voice to unseat the reigning champ in their own game, it’s him.
