Before England manager Gareth Southgate boosted sales of waistcoats across the country with his sharp World Cup outfit, one man was already rocking the look: Line of Duty‘s DS Steve Arnott.


And now the trend seems to have caught on. During filming for Line of Duty series five, actor Martin Compston shared a photograph of him in the famous sleeveless garment – alongside co-star Vicky McClure (DS Kate Fleming) in a similarly dashing waistcoat.

He captioned the image: Flemnott rides again #teamwaistcoat

Jed Mercurio’s fifth series of the police corruption thriller is currently in production and is expected to air in 2019.

We do know that a major new star has joined the cast for Line of Duty series five: Boardwalk Empire actor Stephen Graham.

The BBC announced Graham’s casting in a cryptic e-mail with the subject line, “CCTV image of a suspect AC-12 wish to talk to as part of an ongoing investigation”, accompanied by a picture of the actor pulling off a black balaclava.
