She wasn't even the favourite to win and many thought that she would be one of the first voted out of the final.

But Leanne Mitchell proved that you don't have to have the best odds but just the best vocals as she was crowned the winner of the very first series of The Voice UK.

The 28-year-old from Lowestoft in Suffolk looked utterly stunned as host Holly Willoughby read her name out.

She gasped and put her hand over her mouth as Bo Bruce, who was the hot favourite to win, and Tyler James engulfed her for a hug.

Fighting back tears of joy, she hugged them back and was left speechless, just saying, 'oh my God, oh my God' over and over again.

When Willoughby asked her if she was feeling a new found confidence she said: 'Thank you everyone. I'm starting to believe in myself.'

Tense: Bo Bruce, Leanne and Tyler James waited nervously to hear who had won...

Leanne had started her final show with a solo performance of James Brown's It's A Man's Man's World and afterwards, Sir Tom said she 'steps it up every week', adding: 'She's not frightened to take on different songs and what you see is what you get. She's a very natural person and I think that's why people have kept her in.'

And Danny O'Donoghue simply added: 'It's gonna be a woman's woman's world after that performance! It was a pleasure to be here and listen to that.'

After learning that Vince Kidd had become the first finalist to be voted and knowing she was safe, Leanne joined Sir Tom on stage for their duet of his song Mama Told Me Not To Come.

Having rehearsed at the world-famous music venue Ronnie Scott's in London's Soho, they belted it out on stage, prompting Holly to say: 'I think you've used up our big voice quota for the rest of the night!'

Leanne said to Sir Tom: 'Thank you for singing with me, that was brilliant, it feels amazing.'

And he replied: 'Well, I know I'm gonna be on a talk show one day saying I remember when I sang with Leanne Mitchell. I felt I had the strongest singers with Ruth Brown and Leanne but one of them had to leave so a shout out to Ruth as well.'

Leanne then got to perform one more song before the viewers voted their winner and she chose to serenade them with Whitney Houston's Run To You, which she had already performed in the series.

Sir Tom, who, along with Jessie was in tears, said it was her best performance to date and added: 'It was unbelievable when she sang it last week, she took it somewhere else and tonight she did it again.
