Phillip Schofield nearly lets major Line Of Duty spoiler slip about show’s finale on This Morning

Phillip Schofield nearly let a Line Of Duty spoiler slip as they discussed Sunday’s highly-anticipated finale on This Morning on Tuesday.

The host, 59, said he had to ‘tread carefully’ as he announced that he and Holly Willoughby, 40, would be interviewing a ‘very exciting guest’ next Monday, after the final episode has aired. 

Phillip kept the identity of the star shrouded in mystery, with Holly saying she was relieved it was Phil telling viewers the news and not her, over fear she would reveal a major spoiler.

Showing off her wit, Holly told him: ‘Treading the Line Of Duty would be the thing to say.’

To which Phil laughed and said: ‘That’s exactly what it is. But we do have an exciting guest on Monday. 

A dramatic trailer for the final episode of Line Of Duty released on Monday left fans wondering if the gripping police thriller will return.

It has been five years since anti-corruption police in the AC-12 unit began to hunt a mysterious bent top copper known as H.

Tease: Holly said : 'I'm glad you're saying this and not me because I definitely would have messed that up.' Phil replied: 'I'm treading the line of what we are allowed to say'

The 30-second trailer seemed to indicate viewers will at last learn the identity of H as the sixth series of the BBC1 show draws to a close on Sunday.

The trailer had an element of finality, prompting fans to speculate it could be the end of Line Of Duty.

Superintendent Ted Hastings, played by Adrian Dunbar, says: ‘All of these suspicious deaths were orchestrated by one officer in particular – H, the fourth man.’

Who is H? Line Of Duty will be back on Sunday night and fans are eager to find out whether AC-12 will finally crack the case on the elusive H

The trailer then shows characters who could be H, including Chief Constable Philip Osborne, Deputy Chief Superintendent Patricia Carmichael and former Deputy Chief Inspector Marcus Thurwell – as well as fan favourites Hastings and Detective Inspector Kate Fleming.  

The words ‘Every investigation has led to this’ appear across the screen, with all the letters vanishing apart from an ‘H’.

Other images in the tense clip include Acting Detective Superintendent Joanne Davidson being led out of jail in handcuffs before sitting in a prison van asking: ‘What’s going on?’ The trailer’s conclusion sees Fleming, played by Vicky McClure, and Detective Inspector Steve Arnott (Martin Compston) holding guns, ready to shoot.

And in a teaser released on Monday, viewers can be certain of an action-packed finale episode with a police standoff, the return of balaclava men and that 'definately' misspelling

The future of the hugely popular drama has been unclear for some time, with the BBC and show creator Jed Mercurio failing to confirm another season.

Speaking about more possible series, Mercurio told Radio Times earlier this year: ‘We don’t know. Since probably season four, we’ve been talking to the BBC about the realistic longevity of the series. It’s an ongoing discussion is all I can say.’

Line Of Duty continues on BBC One at 9pm.
