The UK's communications regulator Ofcom has said it will not be investigating complaints about the low-cut dress presenter Holly Willoughby wore on the final of The Voice UK on BBC One last month.

The BBC received over 100 complaints about the black lace maxi dress, with 30 people complaining to Ofcom that the outfit should not have been worn on early evening television.

After the show, a BBC spokesman said: "We're sorry if some viewers found Holly's dress to be unsuitable. Holly enjoys fashion and we felt the dress she wore for the live final of The Voice UK was glamorous and wholly appropriate for the occasion.

"We don't believe it would have gone against audience expectations for a TV spectacle such as this."

Willoughby's This Morning co-host Phillip Schofield tweeted at the time: "139 complaints over Holly's gorgeous Voice dress.

"Let's hope those outraged on behalf of their kids don't take them to the beach this summer...God forbid they might see a woman in a bikini before 9pm and be traumatised by the sight of her cleavage!"
