Eurovision host Graham Norton revealed the act that's "the one to beat" this year during an appearance on BBC Breakfast ahead of the much-anticipated annual music spectacular.

The television presenter is in Vienna preparing for this weekend's grand final, where acts will battle it out to be crowned champion, including UK entry Look Mum No Computer (Sam Battle) with Eins, Zwei, Drei.

Graham joined Breakfast via video link on Friday, May 15 to speak with hosts Charlie Stayt and Naga Munchetty about the contest so far, which has seen live semi-finals take place on Tuesday and Thursday.

When quizzed about his impressions following the semi-finals, he confessed there was one country that is "just brilliant".

The Irish presenter said: "Australia have kind of knocked it out of the park this year. They've got Delta Goodrem who can sing like a dream. It's a kind of old-fashioned Euroviison song but it is excellent and last night in the second semi-final we saw the staging," reports the Liverpool Echo.

He continued: "If people didn't see it I won't spoil it for them. It is just brilliant. I know it's pathetic but I was gasping. It was so good. So I think they might be the ones to beat now."

When Charlie pressed him for his views on the remaining acts, Graham conceded: "I mean the bookies' favourites are Finland and that's one of those songs about a third of the way through you're thinking 'why is this the bookies' favourite?' and then it takes off.

"Behind the scenes - cos there's a lot of fire in the staging - there's all these guys dressed in black rolling round on the floor trying to stop her dress going into the flames making it more dramatic. The bookies are never that wrong so that song will be top 3 anyway."

Graham, who attends all the rehearsals, confessed that while he prepared thoroughly for the big night, there was still plenty of room for the unexpected.

"I hope people understand that I do really love this thing, I'm full of affection for Eurovision but at the same time there are elements that you can just laugh at and go 'ooh look at that, that's terrible!"

When Charlie pressed Graham on the UK entry, he responded: "Sam is doing a great job - he is incredibly twinkly and charismatic on stage. They've done a great job with the staging. I feel for him because it's a really physical performance. I have to say last night the arena loved him. So who knows, we will see on the night."

Eurovision Song Contest is on BBC One on Saturday, May 16 at 8pm
