The Voice UK winner Leanne Mitchell has defended the poor chart performance of her debut single.

Mitchell released a cover of Whitney Houston's Run To You after she won the BBC competition on June 2 but it stalled at No 45 on the UK chart.

"It's been a week and it hasn't had a chance to do anything yet," she told The Daily Star.

The former holiday camp singer signed a record deal with Universal Music as part of her prize and is expected to release her debut album later this year.

"I'm hoping we're going to get a good balance between my own songs and cover versions," she said.

The BBC have claimed that the first series of The Voice UK was a hit after it was announced that the show was the biggest entertainment launch in a decade.

The talent show achieved a consolidated series average of 9.2 million (38.5% share) viewers, making it more successful than the first series of The X Factor, Strictly Come Dancing and I'm A Celebrity.
