'Jon Snow is dead... right now' Game of Thrones actress Natalie Dormer kept fans guessing about the fate of the Lord Commander in the upcoming sixth series in a new interview, released on Tuesday

Dead or alive: Jon Snow - who is played by Kit Harington - is feasibly dead after being stabbed multiple times in the finale of the fifth series, according to the Margaery Tyrell star

Viewers saw Snow - who is played by Kit Harington - meet a grisly end during the closing scenes of the season 5 finale.

He was stabbed repeatedly by Lord Steward of the Night's Watch Bowen Marsh and other black brothers who muttered, 'for the Watch' as they launched into him.

The recently-released season teaser, saw the character dead which Natalie reiterated, insisting even basic medical constraints are applicable in Westeros.

The Margaery Tyrell actress said: 'If you get stabbed that many times, you're dead. There are some basic medical rules that even apply in Westeros so Jon Snow is dead... right now.'

She refused to give any more away which means a comeback hasn't been ruled out.

She added: 'You can't predict Game of Thrones, you can never predict it and obviously we have the new situation this year. It's completely unprecedented. [Author] George [R. R. Martin] hasn't published the next book so it really is new for everyone.'

Natalie isn't the first star to give clues away as to what awaits Snow with Maisie Williams and Kit himself dropping hints about what the future holds for the character.

'Let’s just say that Game of Thrones will remain a part of my life for a while, I’ll probably be in my thirties when it’s over,' the London-born star told Belgium magazine, Humo, back in September.

Additionally, 18-year-old Maisie bemoaned how unpleasant it was having to continuously tell people he wasn't coming back... before hinting that that's exactly what is going to happen, last month.

Speaking to The Upcoming on the red carpet of the London Film Critics’ Circle Awards, she said: 'It was awful, it was really awful, people were so sad about it. And I feel so mean because I speak to people and they’re all like "Jon Snow, is he back?" and it’s like really heartbreaking because people are like "yeah, but he’s coming back though?"'

She added: 'It’s a great twist but I can’t say he’s going to be alive.'
