Martin Compston: age, wife, son, home, Vicky McClure friendship

When a TV detective spends years chasing corruption, you assume the actor behind the badge lives a life of high tension too. But Martin Compston, the Scottish star of Line of Duty, has quietly flipped that script: he now splits his time between a Las Vegas home and London, raising a toddler son with his American wife Tianna, a move that hasn’t dimmed his legendary on-screen chemistry with Vicky McClure.

Born: 8 May 1984 · Age (2024): 40 · Nationality: Scottish · Occupation: Actor and former professional footballer · Known for: Line of Duty (DS Steve Arnott) · Spouse: Tianna

Eleven key facts, one pattern: Compston’s life after Line of Duty is split between two continents, two families, and one enduring partnership with his co-star.

How many children does Martin Compston have?

Martin Compston and his wife Tianna have one son, welcomed after the conclusion of Line of Duty. The Mirror described the toddler as a “toddler son” in 2023 coverage, indicating the child was born in the early 2020s (Mirror). The couple keeps his name and exact birth date private.

Who is Martin Compston’s wife?

Compston married Tianna Chanel Flynn, an American actress. The Mirror identified her as Tianna Chanel Flynn and reported that she is an American actress (Mirror). The couple met through mutual friends and tied the knot in a private ceremony—the exact year has not been confirmed publicly.

What does Martin Compston’s wife do?

Tianna is an actress, though her specific credits are not widely publicised. She splits her time between Las Vegas and the UK with Compston, who told Capital Breakfast that his work is in London while his family life is in the U.S. and Scotland (Capital Breakfast with Roman Kemp).

The implication: For an actor whose schedule demands time in London, the dual-home approach lets Tianna stay close to her family in the U.S. while Compston keeps his career rooted in Britain. It’s a practical trade-off that keeps the marriage intact across the Atlantic.

Where does Martin Compston live now?

Martin Compston lives primarily in Las Vegas, Nevada, with his wife Tianna and their son. He also maintains a place in Greenwich, London, for work. In a 2023 interview with Capital Breakfast, Compston explained that his wife is from Las Vegas and they have a home there, while he spends most of his working time in Britain (Capital Breakfast with Roman Kemp). He described Las Vegas as “effectively our holiday home” and noted that his wife sees Scotland the same way.

The pattern: Compston’s domestic arrangement mirrors that of many British actors with American spouses—a base in the U.S. but a strong tie to the UK for career and family. The difference is that he’s open about the split, describing it as a lifestyle choice rather than a relocation.

Are Vicky McClure and Martin Compston friends?

Yes, Martin Compston and Vicky McClure are close friends. Their bond was cemented during the long run of Line of Duty, where they played partners DS Steve Arnott and DI Kate Fleming. In a joint interview with the Big Issue, McClure said their friendship is “genuine” and that while filming, they “have to live with each other pretty much literally” and eat together every evening (Big Issue).

How did their friendship develop?

The pair share the same birthday—8 May—which Compston says makes them “sort of weirdly close and in sync” (Big Issue). Their WhatsApp group, named “Shalamandro” by McClure’s made-up words, is a running joke (Capital Breakfast). Radio Times has highlighted their “close friendship” (Radio Times via Facebook), and ITV Lorraine called them “best pals” (ITV Lorraine via Facebook).

“We have to live with each other pretty much literally.”

What this means: The Compston-McClure friendship is not a PR construct—it’s a genuine, long-term bond that predates and outlasts the show. For fans, that authenticity is part of what made the on-screen partnership electric.

What is Martin Compston’s age?

Martin Compston was born on 8 May 1984, making him 40 years old as of 2024. The Times confirmed his age as 40 in a 2024 interview (The Times). He shares his birthday with Vicky McClure, who was also born on 8 May—a coincidence they both cite as part of their close connection (Big Issue).

Where was Martin Compston born?

Compston was born in Greenock, Scotland, a town on the River Clyde. He grew up there and later moved to London for his acting career. His Scottish roots are a point of pride, and he remains a supporter of Celtic FC.

“We’re sort of weirdly close and in sync because we have the same birthday.”

The trade-off: Turning 40 in 2024, Compston is in a career transition—no longer the young footballer-turned-actor, but a seasoned TV lead with a family. The age milestone marks a shift from early career momentum to a more deliberate, family-first phase.

What football team does Martin Compston support?

Martin Compston is a lifelong supporter of Celtic FC. He spent his teen years attending Celtic matches with his brother Barry at Parkhead. He is also a former professional footballer, having played as a defender in his youth before an injury and a growing interest in acting led him to change careers.

The catch: Compston’s football past is often mentioned in profiles, but the specific club he played for remains unclear in available sources. He has not publicly named the club he represented professionally.

For Martin Compston, the quiet life after Line of Duty is not an end but a recalibration. He has traded the relentless filming schedule for a bi-continental family life, a toddler son, and a friendship with Vicky McClure that still fills tabloid columns. The implication for fans: the actor who played one of TV’s most intense detectives is now living a deliberately low-key life—and that’s the real story.
