Line of Duty's Shalom Brune-Franklin would want to return for series 7

There has been much talk about whether a seventh series will materialise, after the sixth run tied up the central mystery as to the identity of the fourth man – with Mercurio having so far been coy about the possibility of a return.

And speaking on this week's episode of The Jonathan Ross Show, Brune-Franklin was asked what she thought about the likelihood of another series.

"I don’t think I’m important enough to know the answers to those questions," was her response. "That’s what I practised to say if asked this. I have no idea. I don’t know – I really am not important enough to know the answer. Obviously, yeah [I would want to do it].”

Speaking about joining the likes of Martin Compston, Vicky McClure and Adrian Dunbar in such a well-established cast, Brune-Franklin added that it felt like she "was joining high school a term late or something".

"I was such a fan of the show before," she said. "It was like I’d stepped into my TV screen. Half of me was thinking, ‘OK, you’ve been hired to do a job, focus, get it done', the other half was internally screaming at anything I saw… Adrian Dunbar’s face…”

She added: “I was trying hard not to embarrass myself, call Vicky her real name and not Kate.”

And speaking about the ending – which rather divided opinion amongst fans and critics – she continued: “I loved it. I get so scared to talk about Line of Duty even though it’s finished and done. I still feel like I’m going to give something away. You have to keep the secrets for so long.”

Brune-Franklin will next be seen on our screens alongside Jamie Dornan in BBC One thriller The Tourist – which airs its first episode on New Year's Day.

The Jonathan Ross Show airs at 10.05pm on Saturday 11th December on ITV.
