Plenty of viewers first met Martin Compston as DI Steve Arnott in BBC’s Line of Duty, which makes his years as a professional footballer easy to forget. This piece follows his path from Greenock Morton to Ken Loach’s Sweet Sixteen and on to Mayflies, and it separates what sources confirm from what they do not.

What is the new series with Martin Compston?
The series most sources tie to Compston’s recent work is Mayflies. The BBC Media Centre announced the cast on 25 August 2022, with Compston, Tony Curran and Ashley Jensen in the lead roles, Andrea Gibb adapting Andrew O’Hagan’s novel and Peter Mackie Burns directing (according to BBC Media Centre (official BBC press office)).
Compston plays Jimmy, whose friendship with Tully (Curran) was built on music and film in Scotland in 1986. Decades later, Tully receives a terminal cancer diagnosis and asks for help to end his life (according to Good Housekeeping UK (lifestyle magazine coverage)). The novel behind it won the Waterstones Scottish Book of the Year 2021 (Bustle (entertainment news site)).
- Compston was offered the part about a week before filming, and he has been close friends with Tony Curran for more than 20 years (NME (music and culture magazine)).
- O’Hagan has said the novel is a very personal story, and that Tully is based on his old friend Keith Martin (GoodtoKnow (lifestyle and TV site)).
Timeline signal
- 2021: Line of Duty’s final series aired (according to BBC News (public broadcaster reporting))
- 25 August 2022: BBC announces the Mayflies cast (according to BBC Media Centre (official BBC press office))
- 27 August 2022: Mayflies premieres on BBC Scotland (according to Radio X (UK radio network’s entertainment news))

The next project is a seventh series of Line of Duty. According to Wikipedia (encyclopedia entry), the BBC confirmed it on 18 November 2025, with Compston, Vicky McClure and Adrian Dunbar reprising their roles. Radio Times reported in December 2022 that Dunbar had said everyone was gunning for a seventh season (Radio Times (TV listings magazine)).
Metro is less certain. It reportedly cites a TV insider who expects the season in late January 2027, and it adds that Robert Carlyle joins as a guest lead (according to Metro (national newspaper)).
The series 7 commission rests on an encyclopedia entry, and the air window rests on one tier-2 report. Readers tracking Line of Duty should wait for a BBC schedule before repeating either date as fact.
Which Scottish actor is in the Line of Duty cast?
Martin Compston is the actor who played DI Steve Arnott. The Big Issue reports that Compston was cast after Jed Mercurio’s pitch, and that he nearly pulled out because he was also committed to The Wee Man (according to The Big Issue (street magazine interview)).
According to Hello Rayo (Cool FM career profile), he played the role across six series. The show premiered on BBC Two on 26 June 2012 and moved to BBC One from series four in 2017, according to Wikipedia (encyclopedia entry).
Who did Martin Compston play in Line of Duty?
- Role: DI Steve Arnott, the detective at the centre of the BBC police drama (according to The Big Issue (street magazine interview))
- Writing: Jed Mercurio wrote the entire series and served as producer and executive producer, according to Wikipedia (encyclopedia entry)
- Weight of the part: Compston has said the role is tough at times, since Arnott is the story’s moral compass (BBC Media Centre (2017 press pack))
“I love playing him, I genuinely do. It’s a really tough part at times because he’s the moral compass of the story.”

Are Martin Compston and Vicky McClure friends?
- In December 2022, Compston told Radio Times he would love to work with the cast again, and he called Adrian Dunbar, Vicky McClure and Jed Mercurio some of his closest friends.
- The friendship claim is Compston’s own account. None of the supplied sources independently confirm it.
The trade-off: The on-screen partnership is documented, but the friendship rests on a single interview, so it should be presented as his word rather than an established fact.
The verbatim quotes in this article all come from Compston. The supplied research has no direct, attributable quote from Tony Curran, Andrew O’Hagan or Jed Mercurio, so their views appear only as paraphrase.
What is Martin Compston’s real accent?
None of the supplied sources describe Compston’s accent or how he speaks. The accent is therefore not confirmed or ruled out by any cited material.
The sources do cover his route into acting. BBC Radio 2’s Tracks of My Years programme page records that he was an Aberdeen youth player before signing with Greenock Morton, and that he switched to acting in 2002 (BBC Radio 2 (public radio programme page)). According to Wikipedia (encyclopedia entry), Ken Loach cast him as the lead in Sweet Sixteen after an audition, though he had never acted before.
“It’s set across two timelines and is by far the most emotionally challenging job I’ve ever done.”

- The Rig: Compston stars as Fulmer Hamilton, a communications officer, in Amazon Prime Video’s series, which premiered in January 2023 (according to Radio X (UK radio network’s entertainment news))
- Fear: Compston plays the architect Martyn in the Amazon Prime Video thriller, a role the BBC noted let him work from home in Scotland (according to BBC News (public broadcaster reporting))
The implication: Anyone asking about his accent will find no sourced answer, so the honest answer is that it is undocumented.
Where is Martin Compston’s wife from?
The supplied sources do not confirm the identity, origin, age or marital status of Compston’s wife. Her hometown cannot be stated from this research.
Keeping this section marked as unverified protects the page. Any name, age or hometown would need a named primary source before it appears in print.
How old is Martin Compston’s wife?
- No supplied source gives her age.
- Status: unverified.
Is Martin Compston still married?
- No supplied source confirms his current marital status.
- Status: unverified. The research neither confirms nor denies a marriage.
Personal-life pages often repeat unsourced claims as fact. A spouse, hometown or marriage should not appear in print unless a named primary source confirms it.
The catch: Readers searching for his spouse will find confident-sounding claims that this research cannot support.
Is Martin Compston a millionaire?
No verified net worth figure appears in the supplied research, so a yes or no answer would be guesswork. What the BBC does report is his work rate: in a 2025 profile, BBC News says the now 40-year-old has been barely out of work since Sweet Sixteen, more than two decades earlier (according to BBC News (public broadcaster reporting)).
Steady work is not the same as wealth, and the sources do not link the two. Treat any figure on a fan or aggregator page as unverified.
Martin Compston net worth
- No verified net worth figure appears in the supplied sources.

Where does Martin Compston live?

- The sources do not say where he keeps a permanent home or why he splits time between the two.
The catch: The one sourced residence claim comes from a single broadcaster profile, and nothing in the research explains it further.
