Unforgotten spoilers follow.
Unforgotten's Sanjeev Bhaskar has opened up about his co-star Nicola Walker's replacement on the show's new season.
Following Unforgotten's shock season 4 finale, which saw DCI Cassie Stuart killed off in a car crash, DI Sunny Khan was left alone without a partner for the first time during the series' four-year reign.
Since then, Being Human's Sinéad Keenan has signed on to play his character's next partner.

Speaking to Digital Spy and other press during the BAFTA TV Awards, Bhaskar spoke about his new castmate in the upcoming season 5.
He said: "Sinéad's character has come in as Sunny's boss and it's not the best place that Sunny would wish to be in. So let's just say that's where they kick off."
The actor also touched on Sunny's state of mind at the beginning of season 5 and, predictably so, it sounded like a pretty grim place to be.
"It sort of continues the story a little bit from series 4 so Sunny is dealing with a degree of grief, the loss of his friend and partner, so that has an impact on this story."
Bhaskar went on to add: "In terms of format it's very similar to the others, but there's a range of ages in the suspects, which I don't think has happened before. They're quite different so that's kind of interesting too."

However, despite Bhaskar's character being apprehensive of the new boss in town, Keenan has described the actor behind Sunny as "brilliant and lovely".
Back when news of Keenan's casting broke, the actress had said: "I have long been an admirer of [creator] Chris Lang's work so I am absolutely delighted to be joining the Unforgotten team.
"I'm very much looking forward to working with the extraordinary cast led by the brilliant and incredibly lovely, Sanjeev Bhaskar."
Unforgotten airs on ITV.
