Phillip Schofield hints Line of Duty's H will appear on This Morning after finale

Phillip Schofield teased an "exciting" Line of Duty guest will appear on Monday's This Morning after the show's epic finale at the weekend.

But the presenter, 59, admitted that he had to remain tight-lipped about exactly who that was as it could serve as a major spoiler for Sunday's episode.

Is Phil hinting that the actor playing 'H' could be making an appearance?

Speaking on the ITV daytime show today, he said: "The country is gripped by Line of Duty. We have - and all I'm allowed to say is - on Monday's show we have a very exciting guest pertaining to that show."

Laughing, Holly quipped: "I'm very glad you're saying this, I would definitely mess this up."

"I'm treading the line of what we were told we were allowed to say this morning and I think I've gone right down the middle," Phil admitted.

Holly added with a grin: "Treading the line of duty."

Phil responded: "It is what it is - we do have an exciting guest on Monday."

This comes after the final action-packed trailer was released yesterday teasing H's unveiling.

Opening with a montage of suspicious happenings over the series - from the smashed prison van to the Spanish siege and Gail Vella's murder, Ted's voice can be heard.

"All these suspicious deaths were orchestrated by one officer in particular," he says.

DCI Joanne Davidson is seen being led out in cuffs, while a copy of a transcript is laid out with the word "definate" highlighted.

"H," Ted continues. "The fourth man."

Joanne is seen being transported in a vehicle as she worriedly asks what is going on.

But the prison warden withholds an answer and looks away with a smirk.

A police car chase ensues as members of AC-12 walk out wearing bullet proof vests and holding guns as Ted informs them about what they are about to do.

As Steve and the rest of the team appear to intercept a vehicle, he screams at them to "get down" while holding a gun.

Kate also jumps out of a van holding a gun as she shouts: "Armed police!"

What will happen? Who will die? We'll have to wait another six days to find out..
