Until I Kill You: Who is Delia Balmer's partner David and what else has Kevin Doyle been in?

The chilling true crime drama, Until I Kill You, has been captivating ITV viewers with its portrayal of Delia Balmer's (Anna Maxwell-Martin) survival story after an attack by her axe-murderer boyfriend, John Sweeney (Shaun Evans).

Following Sweeney's incarceration, Delia relocated to a new home where she met David, a local taxi driver.

David was instantly smitten with Delia and invited her over for dinner at his place, an offer which Delia accepted.

Despite their initial connection, with David even buying Delia a new bike and taking her on holiday, the ongoing Sweeney trial loomed in the background.

Frequent arguments ensued between Delia and David as she grappled with moving past her traumatic history. Here's everything we know about David.

Who is the actor behind David?

Kevin Doyle, a 64-year-old English actor renowned for his role as Joseph Molesley in Downton Abbey, portrays David.

Audiences might also recognise him from Happy Valley, where he played Detective Sergeant John Wadsworth.

His other acting credits include The Lakes, Coronation Street and The Crimson Field.

Born in Scunthorpe, Lincolnshire, he currently resides in West Yorkshire with his partner Olwen May.

Is David a real person?

Viewers are curious to find out if Delia and David are still together, but it remains unclear whether David is based on a real-life partner of Delia's.

The documentary, Until I Kill You: The Real Story, set to air after the series concludes, may provide further insight into Delia's other relationships.

Delia, who continues her work as a therapeutic masseuse, opened up prior to the show's debut but refrained from discussing others in her life. Speaking to ITV, she revealed her ongoing struggles with mental health, stating: "I am a perfectionist but my life is opposite of perfect."

She further shared her personal battles, saying: "I often suffer from depression and anxiety, afraid of life and afraid of the future, a compulsive worrier."

Delia also expressed a disconnection with herself: "When I look in the mirror I see a stranger. Certain physical pain, I will have for life. I am stuck. I cannot move on, and cannot go further. Fear holds me back from doing certain things."

Until I Kill You continues on ITV at 9pm
